ALSA: sgio2audio: Improve a size determination in snd_sgio2audio_create()

2017-11-29T08:29:31+00:00

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

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.
Done using Coccinelle

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

Returning an error for all unexpected cases shuts up the 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.
