Create kcontrols for pin jack-detections, which work similarly like
jack-input layer.  Each control will notify when the jack is plugged or
unplugged, and also user can read the value at any time via the normal
control API.

The control elements are created with iface=CARD, so that they won't
appear in the mixer apps.

So far, only the pins that enabled the jack-detection are registered.
For covering all pins, the transition of the common unsol-tag handling
would be needed.  Stay tuned.

Introduce a table containing the pins and their jack-detection states
for avoiding the unnecessary verbs to check the pin status at each time.

When the unsol event is enabled via snd_hda_jack_detect_enable(), it
automatically adds the given NID to the table.  Then the driver supposes
that the codec driver will set the dirty flag appropariately when an
unsolicited event is invoked for that pin.

The behavior for reading other pins that aren't registered in the table
doesn't change.  Only the pins assigned to the table are cached, so far.

In near futre, this table can be extended to use the central place for
the unsolicited events of all pins, etc, and eventually include the
jack-detect kcontrols that replace the current input-jack stuff.

Create a new helper function snd_hda_get_pin_label() for getting a label
string for both input and output pins.  hda_get_input_pin_label() is
obsoleted by this function, and the callers are replaced appropriately
now by this patch.

The Intel HDMI chips (ironlake at least) are found to have ~250ms delay
between the ELD_Valid=1 hotplug event is send and the ELD buffer becomes
actually readable. During the time the ELD buffer is mysteriously all 0.

Fix it by scheduling a delayed work to re-read ELD buffer after 300ms.

memset(eld) clears eld->proc_entry which will leak the struct
snd_info_entry when unloading module.

Fix it by

- set eld->eld_valid to true _after_ all eld fields have been filled

Clean up and fix pwr_nids for 92HD71 / 73 / 83 family codecs; remove
pwr_mapping which was incorrect.

The original pwr_nids support of 92HD83xxx was incorrect and never
actually worked before.  Now we should have things working correctly
without having to hack by DID anymore.

It is also not necessary to explicitly turn on all the pins near the
beginning of patch_stac92hd83xxx() now, the pins will go though
initialization properly.

So far the driver creates the multi-io jacks only when a single output
jack, i.e. no multiple speakers are assigned.  This patch adds the
similar multi-io detection even with multiple speakers are assigned
primarily, so that 5.1-speakers + HP/mic/LI combination can work.

We disabled the check of NO_PRESENCE bit of the default pin-config
in commit f4419172 temporarily.  One problem was that the first
implementation was wrong -- the bit after the shift must be checked.
However, this would still give many regressions on machines with broken
BIOS.  They set this bit wrongly even on active pins.

A workaround is to check whether all pins contain this bit.  As far as
I've checked, broken BIOSen set this bit on all pins, no matter whether
active or not.  In such a case, the driver should ignore this bit check.

When freeing the vmaster master element, we should release slave-links
properly, not only assumig that slaves will be freed soon later.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

When a virtual mater control is created, the driver looks for slave
elements from the assigned card instance.  But this may include the
elements of other codecs when multiple codecs are on the same HD-audio
bus.  This works at the first time, but it'll give Oops when it's once
freed and re-created via reconfig sysfs.

This patch changes the element-look-up strategy to limit only to the
mixer elements of the same codec.
