Apply const prefix to the static jack switch table.

Just for minor optimization and no functional changes.

ALSA: core: Constify snd_device_ops definitions

2020-01-03T08:23:51+00:00

Now we may declare const for snd_device_ops definitions, so let's do
it for optimization.

There should be no functional changes by this patch.

ALSA: fix kernel-doc build warning

2017-10-30T07:10:07+00:00

Fix kernel-doc build error. A symbol that ends with an underscore
character ('_') has special meaning in reST (reStructuredText), so add
a '*' to prevent this error and to indicate that there are several of
these values to choose from.

ALSA: jack: Allow building the jack layer without input device

2016-02-23T08:03:07+00:00

Since the recent integration of kctl jack and input jack layers, we
can basically build the jack layer even without input devices.  That
is, the jack layer itself can be built with conditional to enable the
input device support or not, while the users may enable always
CONFIG_SND_JACK unconditionally.

For achieving it, this patch changes the following:
- A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate
  whether the jack layer supports the input device,
- A few items in snd_jack struct and relevant codes are conditionally
  built upon CONFIG_SND_JACK_INPUT_DEV,
- The users of CONFIG_SND_JACK drop the messy dependency on
  CONFIG_INPUT.

This change also automagically fixes a potential bug in HD-audio
driver Arnd reported, where the NULL or uninitialized jack instance is
dereferenced.

ALSA: jack: Remove MODULE_*() macros

2015-05-21T09:32:51+00:00

The jack interface is statically included in sound core.  Having
doubly module information is rather confusing.

ALSA: jack: don't report input event for phantom jack

2015-04-30T13:21:35+00:00

There is no input_dev for phantom jack, we should not report
input event for it, otherwise, NULL pointer dereference error
will occur.

ALSA: hda - Update to use the new jack kctls method

2015-04-27T19:37:42+00:00

Jack snd_kcontrols can now be created during snd_jack_new()
or by later calling snd_jack_add_new_kctls().

This patch creates the jacks during the initialisation stage
for both phantom and non phantom jacks.

ALSA: jack: extend snd_jack_new to support phantom jack

2015-04-27T19:37:41+00:00

Dont create input devices for phantom jacks.

Here, we extend snd_jack_new() to support phantom jack creating:
pass in a bool param for [non-]phantom flag, and a bool param
initial_jack to indicate whether we need to create a kctl at
this stage.

We can also add a kctl to the jack after its created meaning we
can now integrate the HDA and ASoC jacks.
