2009-11-12pps: events reporting fix upRodolfo Giometti
PPS events must be recorded according to PPS's mode settings. If a process asks for (i.e.) capture-assert events only, when the PPS client calls the pps_event() function to save the current PPS event, we should verify the event type and then discard unwanted ones. Also, without this patch userland processes waiting for a specific PPS event (assert or clear but not both) may be awakened at wrong time.

2009-11-12gpiolib: fix device_create() result checkSergei Shtylyov
In case of failure, device_create() returns not NULL but the error code. The current code checks for non-NULL though which causes kernel oops in sysfs_create_group() when device_create() fails. Check for error using IS_ERR() and propagate the error value using PTR_ERR() instead of fixed -ENODEV code returned now...

2009-11-12rtc: v3020: fix v3020_mmio_read_bit()Scott Valentine
v3020_mmio_read_bit() always returns 0 when left_shift > 7. v3020_mmio_read_bit()'s return type is (unsigned char). The code returns a value masked by (1 << left_shift) that is casted to the return type. If left_shift is larger than 7, the cast will always result in a 0 return value. The problem was discovered with left_shift = 16, and the included patch corrects the problem. The bug was introduced in the last (Apr 3 2009) commit of the file, kernel versions 2.6.30 and later.

2009-11-12fb: remove fb_save_state() and fb_restore_state operationsKrzysztof Helt
Remove fb_save_state() and fb_restore_state operations from frame buffer layer. They are used only in two drivers: 1. savagefb - and cause bug #11248 2. uvesafb Usage of these operations is misunderstood in both drivers so kill these operations, fix the bug #11248 and avoid confusion in the future. Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release). This defeats the purpose of these operations.

2009-11-11btusb bluetooth driver: wait for 'waker' work too before closingLinus Torvalds
Rafael debugged a resume-time hang (with oopses in workqueue handling) on his laptop that was due to the 'waker' workqueue entry being disconnected and then released without the workqueue entry having been synchronized. Several people were involved, with Oleg Nesterov doing a debugging patch showing what workqueue entry was corrupt etc. This was a regression introduced by commit 7bee549e19 ("Bluetooth: Add USB autosuspend support to btusb driver") as Rafael points out (not actually bisected, but it became clear once the bug was found).

This solves a problem in firedtv that has become major for Swedish DVB-T users the last month or so. It will most likely solve issues seen by other users as well. If the length of an AVC message is greater than 127, the length field should be encoded in LV mode instead of V mode. V mode can only be used if the length is 127 or less.

2009-11-07V4L/DVB (13230): s2255drv: Don't conditionalize video buffer completion on ↵Mike Isely
waiting processes The s2255 driver had logic which aborted processing of a video frame if there was no process waiting on the video buffer in question. That simply doesn't work when the application is doing things in an asynchronous manner. If the application went to the trouble to queue the buffer in the first place, then the driver should always attempt to complete it - even if the application at that moment has its attention turned elsewhere. Applications which always blocked waiting for I/O on the capture device would not have been affected by this. Applications which *mostly* blocked waiting for I/O on the capture device probably only would have been somewhat affected (frame lossage, at a rate which goes up as the application blocks less). Applications which never blocked on the capture device (e.g. polling only) however would never have been able to receive any video frames, since in that case this "is anyone waiting on this?" check on the buffer never would have evalutated true. This patch just deletes that harmful check against the buffer's wait queue. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> CC: stable@kernel.org

2009-11-07V4L/DVB (13190): em28xx: fix panic that can occur when starting audio streamingDevin Heitmueller
Because the counters were not reset when starting up streaming, they would be reused from the previous run. This can result in cases such that when the second instance of streaming starts up, the "cnt" variable in em28xx_audio_isocirq() can end up being negative, resulting in attempting to write to memory before the start of runtime->dma_area (as well as having a negative number of bytes to copy).

2009-11-07V4L/DVB (13170): bttv: Fix reversed polarity error when switching video standardMike Isely
The bttv driver function which handles switching of the video standard (set_tvnorm() in bttv-driver.c) includes a check which can optionally also reset the cropping configuration to a default value. It is "optional" based on a comparison of the cropcap parameters of the previous vs the newly requested video standard. The comparison is being done with a memcmp(), a function which only returns a true value if the comparison actually fails. This if-statement appears to have been written to assume wrong memcmp() semantics. That is, it was re-initializing the cropping configuration only if the new video standard did NOT have different cropcap values. That doesn't make any sense. One definitely should reset things if the cropcap parameters are different - if there's any comparison to made at all. The effect of this problem was that a transition from, say, PAL to NTSC would leave in place old cropping setup that made sense for the PAL geometry but not for NTSC. If the application doesn't care about cropping it also won't try to reset the cropping configuration, resulting in an improperly cropped video frame. In the case I was testing this actually caused black video frames to be displayed. Another interesting effect of this bug is that if one does something which does NOT change the video standard and this function is run, then the cropping setup gets reset anyway - again because of the backwards comparison. It turns out that just running anything which merely opens and closes the video device node (e.g. v4l-info) will cause this to happen. One can argue that simply opening the device node and not doing anything to it should not mess with any of its state - but because of this behavior, any TV app which does such things (e.g. xawtv) probably therefore doesn't see the problem. The solution is to fix the sense of the if-statement. It's easy to see how this mistake could have been made given how memcmp() works. The patch is therefore removal of a single "!" character from the if-statement in set_tvnorm in bttv-driver.c.

2009-11-07V4L/DVB (13169): bttv: Fix potential out-of-order field processingMike Isely
There is a subtle interaction in the bttv driver which can result in fields being repeatedly processed out of order. This is a problem specifically when running in V4L2_FIELD_ALTERNATE mode (probably the most common case). 1. The determination of which fields are associated with which buffers happens in videobuf, before the bttv driver gets a chance to queue the corresponding DMA. Thus by the point when the DMA is queued for a given buffer, the algorithm has to do the queuing based on the buffer's already assigned field type - not based on which field is "next" in the video stream. 2. The driver normally tries to queue both the top and bottom fields at the same time (see bttv_irq_next_video()). It tries to sort out top vs bottom by looking at the field type for the next 2 available buffers and assigning them appropriately. 3. However the bttv driver *always* actually processes the top field first. There's even an interrupt set aside for specifically recognizing when the top field has been processed so that it can be marked done even while the bottom field is still being DMAed. Given all of the above, if one gets into a situation where bttv_irq_next_video() gets entered when the first available buffer has been pre-associated as a bottom field, then the function is going to process the buffers out of order. That first available buffer will be put into the bottom field slot and the buffer after that will be put into the top field slot. Problem is, since the top field is always processed first by the driver, then that second buffer (the one after the first available buffer) will be the first one to be finished. Because of the strict fifo handling of all video buffers, then that top field won't be seen by the app until after the bottom field is also processed. Worse still, the app will get back the chronologically later bottom field first, *before* the top field is received. The buffer's timestamps will even be backwards. While not fatal to most TV apps, this behavior can subtlely degrade userspace deinterlacing (probably will cause jitter). That's probably why it has gone unnoticed. But it will also cause serious problems if the app in question discards all but the latest received buffer (a latency minimizing tactic) - causing one field to only ever be displayed since the other is now always late. Unfortunately once you get into this state, you're stuck this way - because having consumed two buffers, now the next time around the "first" available buffer will again be a bottom field and the same thing happens. How can we get into this state? In a perfect world, where there's always a few free buffers queued to the driver, it should be impossible. However if something disrupts streaming, e.g. if the userspace app can't queue free buffers fast enough for a moment due perhaps to a CPU scheduling glitch, then the driver can get momentarily starved and some number of fields will be dropped. That's OK. But if an odd number of fields get dropped, then that "first" available buffer might be the bottom field and now we're stuck... This patch fixes that problem by deliberately only setting up a single field for one frame if we don't get a top field as the first available buffer. By purposely skipping the other field, then we only handle a single buffer thus bringing things back into proper sync (i.e. top field first) for the next frame. To do this we just drop the few lines in bttv_irq_next_video() that attempt to set up the second buffer when that second buffer isn't for the bottom field. This is definitely a problem in when in V4L2_FIELD_ALTERNATE mode. In the other modes this change either has no effect or doesn't harm things any further anyway.
