e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

417f96420a ASoC: rsnd: add callback status check method
R-Car sound can use SSI/SRC/DVC modules, and these are controlled as
rsnd_mod in rsnd driver. These rsnd_mod has each own function as
callback. Basically these callback function has pair like probe/remove,
start/stop, etc. And, these functions are called by order to each stage
like below.
 1. src->probe
 2. ssi->probe
 3. dvc->probe
 4. src->start
 5. ssi->start
 6. dvc->start
 7. src->stop
 8. ssi->stop
 9. dvc->stop
10. src->remove
11. ssi->remove
12. dvc->remove

But, current rsnd driver doesn't care about its status which indicates
which function is called.
For example, if 5) returns error, 6) is not called. In such case,
9) should not be called. This patch care about each modules status.

bc26321404 ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_control
Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.

While we are at it also change the type from int to bool.

The following semantich patch was used for automatic conversion of the
drivers:
// <smpl>
@@
identifier drv;
@@
struct snd_soc_dai_driver drv = {
-	.ac97_control
+	.bus_control

1a7889ca8a ASoC: rsnd: fixup SND_SOC_DAIFMT_xB_xF behavior
In current R-Car rsnd driver,
the SND_SOC_DAIFMT_xB_xF flags are used to HW default behavior,
but, it should be used to specific format.
The waveforms of LEFT_J/RIGHT_J format with
SND_SOC_DAIFMT_NB_NF flag will be
started from "falling edge" without this patch.
But, it should be started from "rising edge".
