2012-03-19[media] STV0288 increase delay between carrier searchMalcolm Priestley
The current delay of 30uS is too short to recover any carrier. In the lmedm04 driver delays were added to overcome carrier lock problems. The typical delay was 30mS (2 x 15ms register write 0x2c and read 0x24). Other drivers that use STV0288 don't appear to have any delay are likely to have also suffered this problem.

2012-03-19[media] v4l: Add custom compat_ioctl32 operationLaurent Pinchart
Drivers implementing custom ioctls need to handle 32-bit/64-bit compatibility themselves. Provide them with a way to do so. To avoid circular module dependencies, merge the v4l2-compat-ioctl32 module into videodev. There is no point in keeping them separate, as the v4l2_compat_ioctl32() function is required by videodev if CONFIG_COMPAT is set anyway.

2012-03-19ASoC: pxa-ssp: atomically set stream active masksDaniel Mack
PXA's SSP engine fails to take its current channel phase into account when enabling a stream while the engine is already running. This results in randomly swapped left/right channels on either the record or the playback side, depending on which one was enabled first. The following patch fixes this by factoring out the bit field modifications in question to a separate function that pauses the engine temporarily, modifies the bits and kicks it off again afterwards. Appearantly, a transition of SSCR0_SSE syncs both directions properly. The patch has been rolled out to quite a number of devices over the last weeks and seems to fix the issue reliably.

2012-03-19EDAC: Correct scrub rate APIBorislav Petkov
The original scrub rate API definition states that if scrub rate accessors are not implemented, a negative value (-1) should be written to the sysfs file (/sys/devices/system/edac/mc/mc<N>/sdram_scrub_rate, where N is the memory controller number on the system). This is counter-intuitive and awkward at the very least because, when setting the scrub rate, userspace has to write to sysfs and then read it back to check error status of the operation. As Tony notes, best it would be to not have the sdram_scrub_rate in sysfs if scrub rate support is not implemented. It is too late about that and a bunch of drivers on a bunch of arches would need to be changed and tested which is not a trivial task ATM. Instead, settle for the next best thing of returning -ENODEV when implementation is missing and -EINVAL when there was an error encountered while setting the scrub rate.
