2015-10-22[media] m88ds3103: use own reg update_bits() implementationAntti Palosaari1-26/+47
Device stopped to tuning some channels after regmap conversion. Reason is that regmap_update_bits() works a bit differently for partially volatile registers than old homemade routine. Return back to old routine in order to fix issue.

2015-10-22[media] rtl28xxu: fix control message flawsAntti Palosaari2-3/+14
Add lock to prevent concurrent access for control message as control message function uses shared buffer. Without the lock there may be remote control polling which messes the buffer causing IO errors. Increase buffer size and add check for maximum supported message length.

Moreover if the segment is not outside the firmware file then also we have been returning the garbage.

Add AC'97 support to fsl-asoc-card using generic ASoC AC'97 CODEC. The SSI controller will silently enable any TX AC'97 slots that have their bits set in SLOTREQ received from CODEC and then will redirect some of playback samples there. That's why it is important to make sure that any of CODEC playback slots that can pull samples are set to slots 3/4 (standard PCM playback slots). Currently, this applies to S/PDIF slots as they were seen to pull samples sometimes even with S/PDIF output being disabled.

2015-10-22ASoC: Document DAI signal polarityAnatol Pomozov1-1/+16
Currently there is no clear definition of what FSYNC polarity is. Different drivers use its own definition of what is "normal" and what is "inverted" fsync. This leads to compatibility problems between drivers. For example TegraX1 driver assumes that DSP-A format with frames starting at rising FSYNC edge has "inverted" polarity, while RT5677 assumes it is "normal" polarity. Explicitly specify meaning of BCLK/FSYNC polarity to avoid future compatibility problems. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-10-22ALSA: Remove transfer_ack_{begin,end} callbacks from struct snd_pcm_runtimeLars-Peter Clausen3-26/+2
While there is nothing wrong with the transfer_ack_begin and transfer_ack_end callbacks per-se, the last documented user was part of the alsa-driver 0.5.12a package, which was released 14 years ago and even predates the upstream integration of the ALSA core and has subsequently been superseded by newer alsa-driver releases. This seems to indicate that there is no need for having these callbacks and they are just cruft that can be removed.

Commit 8eb934591f8b ("btrfs: check unsupported filters in balance arguments") adds a jump to exit label out_bargs in case the argument check fails. At this point in addition to the bargs memory, the memory for struct btrfs_balance_control has already been allocated. Ownership of bctl is passed to btrfs_balance() in the good case, thus the memory is not freed due to the introduced jump. Make sure that the memory gets freed in any case as necessary.
