ALSA: core: Fix kernel-doc warnings

2016-11-15T06:28:18+00:00

Several lines in sound/core.h get the kernel-doc warnings like

  ./include/sound/core.h:323: warning: No description found for parameter '...'

where we use define like foo(x, args...) and "args" isn't mentioned in
the comments.  As an easy workaround, use simple __VA_ARGS__ for VLA
in macros.

ALSA: hda_intel: add card number to irq description

2016-01-12T20:05:16+00:00

Currently the info in /proc/interrupts doesn't allow to figure out which
interrupt belongs to which card (HDMI, PCH, ..).
Therefore add card details to the interrupt description.
With the patch the info in /proc/interrupts looks like this:

PCI-MSI 442368-edge      snd_hda_intel:card1
PCI-MSI 49152-edge      snd_hda_intel:card0

NOTE: this patch adds the new irq_descr field snd_card struct that is
filled automatically at a card object creation.  This can be used
generically for other drivers as well.  The changes for others will
follow later -- tiwai

ALSA: core: Remove superfluous exit calls for proc entries

2015-04-24T15:31:04+00:00

Since each proc entry is freed automatically by the parent, we don't
have to take care of its life cycle any longer.  This allows us to
reduce a few more lines of codes.

ALSA: core: Re-add snd_device_disconnect()

2015-03-03T10:26:28+00:00

Revive snd_device_disconnect() again so that it can be called from the
individual driver.  This time, HD-audio will need it.

ALSA: Add a helper to add a new attribute group to card

2015-02-06T08:56:33+00:00

For assigning sysfs entries for a card device from the driver,
introduce a new helper function, snd_card_add_dev_attr().  In this
way, we can avoid the possible race between the device registration
and the sysfs addition / removal.

The driver can pass a new attribute group to add freely.  This has to
be called before snd_card_register().

Currently, up to two extra groups can be added.  More than that, it'll
return an error.

ALSA: Drop snd_get_device() helper

2015-02-02T16:01:38+00:00

Since the device is no longer hidden but embedded into each component,
we no longer need snd_get_device().  Let's drop it and relevant codes.

ALSA: Simplify snd_device_register() variants

2015-02-02T16:01:26+00:00

Now that all callers have been replaced with
snd_device_register_for_dev(), let's drop the obsolete device
registration code and concentrate only on the code handling struct
device directly.  That said,

- remove the old snd_device_register(),
- rename snd_device_register_for_dev() with snd_device_register(),
- drop superfluous arguments from snd_device_register(),
- change snd_unregister_device() to pass the device pointer directly

ALSA: control: Embed struct device

2015-02-02T13:42:41+00:00

This patch embeds a struct device for the control device into the card
object and avoid the device creation at registration time.

2015-02-02T13:42:33+00:00

Introduce a new helper function snd_device_initialize() to initialize
the device object for sound devices.
