2009-01-29V4L/DVB (10222): zoran: Better syntax for initializing array module paramsTrent Piepho
When initializing a module parameter that is a per-card array, use "{ [0 ... (BUZ_MAX-1)] = -1 }" instead of "{ -1, -1, -1, -1 }". This way all of the entries will be correctly set to -1 if someone changes BUZ_MAX to a value other than 4. Adjust some of the parameter help text too.

2009-01-29V4L/DVB (10219): saa7134: Prevent Oops due to stale IRQ status when enabling ↵Andy Walls
interrupts When enabling a shared IRQ line, then saa7134_irq handler could be invoked before the driver had completely set up internal structures, due to a shared interrupt line firing. Clear the saa7134 interrupt status reg, before requesting the irq line, so that stale IRQ status isn't processed before the internal structures are set up. Marcin Slusarz recently brought this Oops to the attention of the v4l-dvb lists and provided an initial analysis by investigating reports found here: http://kerneloops.org/guilty.php?guilty=mute_input_7133&version=2.6.27-release&start=1802240&end=1835007&class=oops Reported-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

only cards Analog support for HVR-1250 has not been completed, but does exist for the HVR-1800. Since both cards use the same driver, it tries to create the analog dev for both devices, which is not possible. This causes a NULL error to show up in video_open and mpeg_open. -Mark Iterations through the cx23885_devlist must check for NULL pointers as some supported devices only have DVB support at the moment.

2009-01-29V4L/DVB (10209): tveeprom: Properly initialize tuner type (BZ#11367)Mauro Carvalho Chehab
If Hauppauge eeprom is corrupted, the driver returns tuner = 0, instead of TUNER_ABSENT. This makes the drivers to initialize tuner, instead of handling the manual parameter. Since the tuner core rejects that a tuner to have their type changed, this breaks the manual tuner override. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-01-29V4L/DVB (9054): implement proper locking in the dvb ca en50221 driverMatthias Dahl
Concurrent access to a single DVB CA 50221 interface slot is generally discouraged. The underlying drivers (budget-av, budget-ci) do not implement proper locking and thus two transactions could (and do) interfere with on another. This fixes the following problems seen by others and myself: - sudden i/o errors when writing to the ci device which usually would result in an undefined state of the hw and require a software restart - errors about the CAM trying to send a buffer larger than the agreed size usually also resulting in an undefined state of the hw Due the to design of the DVB CA 50221 driver, implementing the locks in the underlying drivers would not be enough and still leave some race conditions, even though they were harder to trigger.

2009-01-08V4L/DVB (10190): cx88: Fix some Kbuild troublesMauro Carvalho Chehab
As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.

2009-01-07USB: change interface to usb_lock_device_for_reset()Alan Stern
This patch (as1161) changes the interface to usb_lock_device_for_reset(). The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe.

2009-01-06poll: allow f_op->poll to sleepTejun Heo
f_op->poll is the only vfs operation which is not allowed to sleep. It's because poll and select implementation used task state to synchronize against wake ups, which doesn't have to be the case anymore as wait/wake interface can now use custom wake up functions. The non-sleep restriction can be a bit tricky because ->poll is not called from an atomic context and the result of accidentally sleeping in ->poll only shows up as temporary busy looping when the timing is right or rather wrong. This patch converts poll/select to use custom wake up function and use separate triggered variable to synchronize against wake up events. The only added overhead is an extra function call during wake up and negligible. This patch removes the one non-sleep exception from vfs locking rules and is beneficial to userland filesystem implementations like FUSE, 9p or peculiar fs like spufs as it's very difficult for those to implement non-sleeping poll method. While at it, make the following cosmetic changes to make poll.h and select.c checkpatch friendly. * s/type * symbol/type *symbol/ : three places in poll.h * remove blank line before EXPORT_SYMBOL() : two places in select.c Oleg: spotted missing barrier in poll_schedule_timeout() Davide: spotted missing write barrier in pollwake() Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Eric Van Hensbergen <ericvh@gmail.com> Cc: Ron Minnich <rminnich@sandia.gov> Cc: Ingo Molnar <mingo@elte.hu> Cc: Christoph Hellwig <hch@infradead.org> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Cc: Davide Libenzi <davidel@xmailserver.org> Cc: Brad Boyer <flar@allandria.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Roland McGrath <roland@redhat.com> Cc: Mauro Carvalho Chehab <mchehab@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Davide Libenzi <davidel@xmailserver.org> Cc: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-01-06Check fops_get() return valueLaurent Pinchart
Several subsystem open handlers dereference the fops_get() return value without checking it for nullness. This opens a race condition between the open handler and module unloading. A module can be marked as being unloaded (MODULE_STATE_GOING) before its exit function is called and gets the chance to unregister the driver. During that window open handlers can still be called, and fops_get() will fail in try_module_get() and return a NULL pointer. This change checks the fops_get() return value and returns -ENODEV if NULL.

2009-01-03V4L/DVB (10173): Missing v4l2_prio_close in radio_releaseUdo Steinberg
The radio_release function of the BTTV driver is missing a call to v4l2_prio_close. As a result, after the radio device has been opened at least once (e.g., by HAL during bootup), v4l2_priority will never drop below V4L2_PRIORITY_INTERACTIVE again. With the following patch against 2.6.28, applications that run with V4L2_PRIORITY_BACKGROUND are able to open devices again. Previous Linux versions are affected as well.

2009-01-02V4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by ↵Michael Krufky
zero error A user reported the following OOPS with his pcHDTV HD5500 card, which uses a cx88 PCI bridge with a LG-TDVS-H06xF frontend module, made up of a TUA6034 tuner, TDA988x IF demod, and LG DT3303 ATSC/QAM demod. Somehow, tuner-core gets loaded before the digital driver configures the tuner, and tuner-core somehow incorrectly sets the tuner type to LG NTSC (TAPE series) instead of LG TDVS-H06xF. This tuner type does not have the tuning stepsize defined, so an OOPS occurs during the digital tune function. We still dont know how the type gets set incorrectly in the first place. The user has a tainted kernel with a binary nividia module, which COULD have something to do with this, but it's hard to say for sure. Nevertheless, to avoid this division by zero, we should check that stepsize is defined. If stepsize is not defined, print an error and bail out on the tune request. cx8800 0000:05:01.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]: subsystem: 7063:5500, board: pcHDTV HD5500 HDTV [card=47,autodetected], frontend(s): 1 cx88[0]: TV tuner type 47, Radio tuner type -1 tuner' 2-0043: chip found @ 0x86 (cx88[0]) tda9887 2-0043: creating new instance tda9887 2-0043: tda988[5/6/7] found tuner' 2-0061: chip found @ 0xc2 (cx88[0]) tuner-simple 2-0061: creating new instance tuner-simple 2-0061: type set to 47 (LG NTSC (TAPE series)) cx88[0]/0: found at 0000:05:01.0, rev: 5, irq: 19, latency: 32, mmio: 0xea000000 cx88[0]/0: registered device video1 [v4l2] cx88[0]/0: registered device vbi1 cx88_audio 0000:05:01.1: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]/1: CX88x/0: ALSA support for cx2388x boards cx88[0]/2: cx2388x 8802 Driver Manager cx88-mpeg driver manager 0000:05:01.2: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]/2: found at 0000:05:01.2, rev: 5, irq: 19, latency: 32, mmio: 0xec000000 cx8802_probe() allocating 1 frontend(s) cx88/2: cx2388x dvb driver version 0.0.6 loaded cx88/2: registering cx8802 driver, type: dvb access: shared cx88[0]/2: subsystem: 7063:5500, board: pcHDTV HD5500 HDTV [card=47] cx88[0]/2: cx2388x based DVB/ATSC card tuner-simple 2-0061: attaching existing instance tuner-simple 2-0061: type set to 64 (LG NTSC (TAPE series)) tda9887 2-0043: attaching existing instance DVB: registering new adapter (cx88[0]) DVB: registering adapter 0 frontend 0 (LG Electronics LGDT3303 VSB/QAM Frontend)...
