In some cases, the fix-up is required in the init callback to be called
both at the first initialization and at the resume.  The new action type
ALC_FIXUP_ACT_INIT is used for this case.

So far, only ALC275_FIXUP_SONY_HWEQ uses this.

Instead of keeping various data types in a single record, put the
type field and keep a single value in each entry, but allows chaining
multiple fixup entries.  This allows more flexible data management
(see ALC275_FIXUP_SONY_HWEQ for example).

The dynamic PCM restriction based on ELD information may lead to the
problem in some cases, e.g. when the receiver is turned off.  Then it
may send a TV HDMI default such as channels = 2.  Since it's still
plugged, the driver doesn't know whether it's the right configuration
for future use.  Now, when an app opens the device at this moment,
then turn on the receiver, the app still sends channels=2.

The right solution is to implement some kind of notification and
automatic re-open mechanism.  But, this is a goal far ahead.

This patch provides a workaround for such a case by providing a new
module option static_hdmi_pcm for snd-hda-codec-hdmi module.  When
this is set to true, the driver doesn't change PCM parameters per
ELD information.  For users who need the static configuration like
the scenario above, set this to true.

The parameter can be changed dynamically via sysfs, too.

So far, Realtek auto-parser assumed that the multiple pins are only for
line-outs, and assigned the channel names like Front, Surround, etc for
the multiple outputs.  But, there are devices that have multiple
headphones, and these can be better controlled with the corresponding
control-name like "Headphone" with indicies.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

When multiple headphone pins are defined without line-out pins, the
driver takes them as primary outputs.  But it forgot to set line_out_type
to HP by assuming there is some rest of HP pins.  This results in some
mis-handling of these pins for Realtek codec parser.  It takes as if
these are pure line-out jacks.

The load_mixer_volumes() function, which can be triggered by
unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to
a buffer overflow.  Because the provided "name" argument isn't
guaranteed to be NULL terminated at the expected 32 bytes, it's possible
to overflow past the end of the last element in the mixer_vols array.
Further exploitation can result in an arbitrary kernel write (via
subsequent calls to load_mixer_volumes()) leading to privilege
escalation, or arbitrary kernel reads via get_mixer_levels().  In
addition, the strcmp() may leak bytes beyond the mixer_vols array.
