Pull driver core update from Greg KH: "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.

2014-12-03ASoC: rsnd: add callback status check methodKuninori Morimoto2-3/+38
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.

2014-11-18ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_controlLars-Peter Clausen1-1/+1
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 = - 1 + true }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
