Subject: [PATCH v3 0/2] Support mute notifications for CS35L41 HDA

Some systems use a special keyboard shortcut to mute speaker audio.
On systems using CS35L41 HDA which have this shortcut, add a
mechanism which uses ACPI notifications to determine when the
shortcut is pressed, and then mute the amps inside the driver.

Since this is not a normal mute mechanism, it does not go through
userspace. To allow userspace to be able to track this special
state, add an ALSA control which tracks the state of this forced
mute

Changes since v2:
- Fixed compile issue when CONFIG_ACPI is missing

Stefan Binding (1):
  ALSA: hda: cs35l41: Add read-only ALSA control for forced mute

  ALSA: hda: cs35l41: Support mute notifications for CS35L41 HDA
