      ALSA: hda - Fix silent headphone on Thinkpads with AD1984A codec · 1ac32930
      Takashi Iwai authored 
      AD1984A codec has a couple of pins with EAPD controls, and the generic
codec driver tries to turn each of them on/off depending on the pin
active state.  However, Thinkpads seem to use EAPD of the speaker pin
as a master EAPD for controlling the mute of all outputs, including
the headphone.  This results in the dead headphone output via the
headphone plugging because it mutes the speaker and turns off EAPD.

The fix is to simply add spec->gen.keep_on_eapd flag.

[This is a regression fix on 3.12 where we moved the AD codec parser
 to the generic parser.  3.11 and earlier didn't show this problem
 because still static quirks have been used.]

      ALSA: hda - Add missing initial vmaster hook at build_controls callback · b63eae0a
      Takashi Iwai authored 
      The generic parser has a support of vmaster hook, but this is
initialized only in the init callback with the check of the presence
of the corresponding kctl.  However, since kctl is NULL at the very
first init callback that is called before build_controls callback, the
vmaster hook sync is skipped there.  Eventually this leads to the
uninitialized state depending on the hook implementation.

This patch adds a simple workaround, just calling the sync function
explicitly at build_controls callback.

      ALSA: hda - Fix unbalanced runtime PM refcount after S3/S4 · e6bbe666
      Takashi Iwai authored 
      When a machine goes to S3/S4 after power-save is enabled, the runtime
PM refcount might be incorrectly decreased because the power-down
triggered soon after resume assumes that the controller was already
powered up, and issues the pm_notify down.

This patch fixes the incorrect pm_notify call simply by checking the
current value properly.

      ALSA: us122l: Fix pcm_usb_stream mmapping regression · ac536a84
      Takashi Iwai authored 
      The pcm_usb_stream plugin requires the mremap explicitly for the read
buffer, as it expands itself once after reading the required size.
But the commit [314e51b9: mm: kill vma flag VM_RESERVED and
mm->reserved_vm counter] converted blindly to a combination of
VM_DONTEXPAND | VM_DONTDUMP like other normal drivers, and this
resulted in the failure of mremap().

For fixing this regression, we need to remove VM_DONTEXPAND for the
read-buffer mmap.
