2012-10-24USB: usb-skeleton.c: fix compilation error and restored kref_put on fail in ↵Constantine Shulyupin
skel_open Fixing compilaton error. Incrementing usage counter only on successful execution of skel_open. Removing redundant locking Some last changes in function skel_open and finally commit 52a7499 Revert "USB: usb-skeleton.c: fix open/disconnect race" introduced a bug in function skel_open, which this patch fixes. Changes since v2: - refactoring - Removing redundant mutex synchronization. Changes since v1: - Fixed accordingly feedback of Oliver Neukum oneukum@suse.de: also need to drop the lock.

2012-10-22OHCI: implement new semantics for URB_ISO_ASAPAlan Stern
This patch (as1614) updates the isochronous scheduling in ohci-hcd to match the new semantics for URB_ISO_ASAP. Testing revealed a hardware bug in the way my OHCI controller handles expired isochronous TDs; consequently the patch tries hard to avoid creating them (unlike the ehci-hcd and uhci-hcd drivers).

2012-10-22EHCI: use the isochronous scheduling thresholdAlan Stern
This patch (as1609) changes the way ehci-hcd uses the "Isochronous Scheduling Threshold" in its calculations. Until now the code has ignored the threshold except for certain Intel PCI-based controllers. This violates the EHCI spec. The new code takes the threshold into account always, removing the need for the fs_i_thresh quirk flag. In addition it implements the "full frame cache" setting more efficiently, moving forward only as far as the next frame boundary instead of always moving forward 8 microframes.

2012-10-22EHCI: improved logic for isochronous schedulingAlan Stern
This patch (as1608) reworks the logic used by ehci-hcd for scheduling isochronous transfers. Now the modular calculations are all based on a window that starts at the last frame scanned for isochronous completions. No transfer descriptors for any earlier frames can possibly remain on the schedule, so there can be no confusion from schedule wrap-around. This removes the need for a "slop" region of arbitrary size. There's no need to check for URBs that are longer than the schedule length. With the old code they could throw things off by wrapping around and appearing to end in the near future rather than the distant future. Now such confusion isn't possible, and the existing test for submissions that extend too far into the future will also catch those that exceed the schedule length. (But there still has to be an initial test to handle the case where the schedule already extends as far into the future as possible.) Delays caused by IRQ latency won't confuse the algorithm unless they are ridiculously long (over 250 ms); they will merely reduce how far into the future new transfers can be scheduled. A few people have reported problems caused by delays of 50 ms or so. Now instead of failing completely, isochronous transfers will experience a brief glitch and then continue normally. (Whether this is truly a good thing is debatable. A latency as large as 50 ms generally indicates a bug is present, and complete failure of audio or video transfers draws people's attention pretty vividly. Making the transfers more robust also makes it easier for such bugs to remain undetected.) Finally, ehci->next_frame is renamed to ehci->last_iso_frame, because that better describes what it is: the last frame to have been scanned for isochronous completions.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus usb: fixes for v3.7-rc2 Here's the first set of fixes for v3.7-rc cycle. DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long standing bug which would keep endpoint with BUSY flag set forever if we cancel a transfer which has already been started by the controller. The second fix will just switch PHYs back off when DWC3 driver is removed. MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when removing a device. For some reason that particular device can fall into a situation where you have both Disconnect and Endpoint IRQs happen simultaneously (have both bits set in IRQ_STATUS register) and, because Disconnect Interrupt is handled before Endpoint Interrupts, we would try to transfer data over a disconnected device, thus generating a kernel oops. Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on the pipe iterator implementation and b) fixing Interrupt Status Clear procedure in order to properly clear a single Interrupt event without clearing (and masking) other events we didn't handle yet.

2012-10-18USB: io_ti: fix sysfs-attribute creationJohan Hovold
Make sure port data is initialised before creating sysfs attributes to avoid a race. A recent patch ("USB: io_ti: fix port-data memory leak") got the sysfs-attribute creation and port-data initialisation ordering wrong.
