ALSA: mips: constify snd_pcm_ops structures

2017-08-19T09:02:18+00:00

snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by  work with
const snd_pcm_ops. So mark the non-const structs as const.

ALSA: mips: make snd_pcm_hardware const

2017-08-17T10:44:14+00:00

Make these const as they are only used in a copy operation.

ALSA: hal2: switch to dma_alloc_attrs

2017-06-16T09:10:05+00:00

Use dma_alloc_attrs directly instead of the dma_alloc_noncoherent wrapper.

ALSA: declare snd_kcontrol_new structures as const

2017-05-30T08:29:25+00:00

Declare snd_kcontrol_new structures as const as they are only passed an
argument to the function snd_ctl_new1. This argument is of type const,
so snd_kcontrol_new structures having this property can be made const.
Done using Coccinelle:

identifier x;

static struct snd_kcontrol_new x@p={...};

ALSA: mips: Deliver indirect-PCM transfer error

2017-05-25T21:34:46+00:00

Now that the indirect-PCM transfer helper gives back an error, we
should return the error from ack callbacks.

ALSA: mips: avoid potential uninitialized variable use

2017-01-16T13:33:42+00:00

MIPS allmodconfig results in this warning:

ALSA: Remove deprecated AU1X00 AC97 driver

2016-02-08T07:17:15+00:00

The AU1X00 AC97 ALSA driver was deprecated in commit 7137c6bcb7ff ("ALSA:
deprecate MIPS AU1X00 AC97 driver") in favor of the newer and better ASoC
driver for the same hardware. This was almost 5 years ago and this driver
has not been in use in the mainline kernel since, it should be safe to
remove it at this point.

Return a negative error code on failure.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

//

identifier ret; expression e1,e2;

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

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.

  Everything has been in linux-next for a while"
