2015-01-02ALSA: riptide: Remove always NULL parameterLars-Peter Clausen
snd_riptide_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-01-02ALSA: wss: Remove (almost) always NULL parametersLars-Peter Clausen
Most callers of snd_wss_pcm(), snd_wss_timer() and snd_cs4236_pcm() pass NULL as the last parameter, some callers pass a pointer but never use it after the function has been called and only a few callers pass a pointer and actually use it. The later is only the case for snd_wss_pcm() for snd_cs4236_pcm() and it is possible to get the same PCM object by accessing the pcm field of the snd_wss struct that was passed as the first parameter. This function removes the last parameters from the functions mentioned above and updates the callers which used it to use chip->pcm instead. This allows us to slightly simplify the functions since they don't have to check and set the last parameter anymore which makes the code slightly shorter and cleaner.

2014-12-30ALSA: Add support for wildcard msbits constraintsLars-Peter Clausen
Currently the msbits constraints requires to specify a specific sample format width for which the constraint should be applied. But often the number of most significant bits is not sample format specific, but rather a absolute limit. E.g. the PCM interface might accept 32-bit and 24-bit samples, but the DAC has a 16-bit resolution and throws away the LSBs. In this case for both 32-bit and 24-bit format msbits should be set to 16. This patch extends snd_pcm_hw_constraint_msbits() so that a wildcard constraint can be setup that is applied for all formats with a sample width larger than the specified msbits. Choosing the wildcard constraint is done by setting the sample width parameter of the function to 0. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-12-30ALSA: Fix handling of multiple msbits constraints on the same runtimeLars-Peter Clausen
If the sound card is made up of discrete components, each with their own driver (e.g. like in the ASoC case), we might end up with multiple msbits constraint rules installed. Currently this will result in msbits being set to whatever the last rule set it to. This patch updates the behavior of the rule to choose the minimum (other than zero) of all the installed rules.

2014-12-27ALSA: atmel: fix building the ac97 driver for at91-multiplatformArnd Bergmann
at91 will no longer export the mach/cpu.h and mach/hardware.h header files in the future, which would break building the atmel ac97c driver. Since the cpu_is_* check is only used to find out whether we are running on avr32 or arm/at91, we can hardcode that check in the ARM case.

The instrument layer codes have been dropped years ago, but this file was left intentionally with a slight hope for the new implementations. But, looking at the reality, the probability we'll have a new code for ISA GUS board is very low, and I won't bet it. So, rather clean this legacy stuff up.

2014-12-26ALSA: hda_controller: Separate stream_tag for input and output streams.Rafal Redzimski
Implemented separate stream_tag assignment for input and output streams. According to hda specification stream tag must be unique throughout the input streams group, however an output stream might use a stream tag which is already in use by an input stream. This change is necessary to support HW which provides a total of more than 15 stream DMA engines which with legacy implementation causes an overflow on SDxCTL.STRM field (and the whole SDxCTL register) and as a result usage of Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.
