      ALSA: hda - Fix invalid multi-io creation on VAIO-Z laptops · da96fb5b
      Takashi Iwai authored 
      VAIO-Z laptops need to use the specific DAC for the speaker output
by some unknown reason although the codec itself supports the flexible
connection.  So we implemented a workaround by a new flag,
no_primary_hp, for assigning the speaker pin first.

This worked until 3.8 kernel, but it got broken because the driver
learned for a better multi-io pin mapping, and not it can assign two
mic pins for multi-io.  Since the multi-io requires to be the primary
output, the hp and two mic pins are assigned in prior to the speaker
in the end.

Although the machine has two mic pins, one of them is used as a noise-
canceling headphone, thus it's no real retaskable mic jack.  Thus, at
best, we can disable the multi-io assignment and make the parser
behavior back to the state before the multi-io.

This patch adds again a new flag, no_multi_io, to indicate that the
device has no multi-io capability, and set it in the fixup for
VAIO-Z.  The no_multi_io flag itself can be used generically, added
via a helper line, too.

      ALSA: hda - Remove analog mic pin override from STAC9228 dell-bios quirk · eefb8be4
      Takashi Iwai authored 
      The current fixup for dell-bios model with STAC9228 codec contains the
override of pin 0x0c for analog mic.  But this is actually just adding
a bogus pin and confuses the parser.  Better to remove it for the
auto-mic switching.

Meanwhile, for a possible regression, keep the old configuration as
model=dell-bios-amic, so that people can test it again quickly.

Tested on Dell 1420n laptop.

      ALSA: hda - WAKEEN feature enabling for runtime pm · 7d4f606c
      Wang Xingchao authored 
      With runtime power save feature enabled, Headphone hotplug
event will not be detected while controller/codec in D3. HDA has
feature WAKEEN to let codec wake up system if controller is in D3 or
system in S3.(HDA Spec 4.5.9.2/3). Codec can send out INT or wake up
controller depending on whether CIE or GIE enabled.(Figure 4, Interupt
structure).

The controller must be in RESET mode after enter runtime-suspend, otherwise
it will not be waken up even if codec send out wake-up event. And STATESTS
will be cleared after controller brought out of RESET mode.

This patch only enable WAKEEN for runtime-suspend(Controller D3) mode,
not for system S3 mode. with tool "evtest", Headphone hotplug events
could be cought and reported successfully.

      ALSA: hda - jack poll once if jackpoll_interval==0 · 18e60627
      Wang Xingchao authored 
      With jackpoll_interval != 0, it's used to poll jack event periodically
in a delayed work. if it's 0, give the caller chance to probe jack status
but will not restart the delayed work.

In the next patch which enable WAKEEN feature, HDA controller was able to wake
up system when it's in D3, it's useful to detect Jack hotplug event and notify
userspace. By default the jackpoll_interval=0, this patch let jack poll once
without starting the delayed work.

      ALSA: usx2y: remove an unneeded check · 85054b21
      Dan Carpenter authored 
      The test here is always true because S[i].urb is an array not a pointer.
Also it's bogus because the intent was to test:
	if (S->urb[i]) {
instead of:
	if (S[i].urb) {

Anyway, usb_kill_urb() and usb_free_urb() accept NULL pointers so we can
just remove this.

      ALSA: hda - Add snd_hda_jack_detect_state() helper function · 60ea8ca2
      Takashi Iwai authored 
      snd_hda_jack_detect() function returns a boolean value for a jack
plugged in or not, but it also returns always true when the
corresponding pin is phantom (i.e. fixed).  This is OK in most cases,
but it makes the generic parser misbehaving about the auto-mute or
auto-mic switching, e.g. when one of headphone pins is a fixed.
Namely, the driver decides whether to mute the speaker or not, just
depending on the headphone plug state: if one of the headphone jacks
is seen as active, then the speaker is muted.  Thus this will result
always in the muted speaker output.

So, the problem is the function returns a boolean, after all, although
we need to think of "phantom" jack.  Now a new function,
snd_hda_jack_detect_state() is introduced to return these tristates.
The generic parser uses this function for checking the headphone or
mic jack states.

Meanwhile, the behavior of snd_hda_jack_detect() is kept as is, for
keeping compatibility in other driver codes.

Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)

Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.

As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?
