ALSA: compress_core: don't return -EBADFD from poll if paused
Pausing audio playback is not an illegal state so it doesn't
seem sensible for poll() to return -EBADFD on a paused stream.
There's also no reason to assume that we can't write more data
to the DSP while playback is paused. Remove the -EBADFD so that
a stream in paused state will still report the buffer
availability from poll(). It is up to the user process to
manage its state so that it knows whether it is paused or not.
The ATI/AMD video/audio latencies are specified in apparent HDMI VSDB
format. In this format values above 251 are not valid (or stream
component is not supported - 255), but no checking is performed since
this was not mentioned in the AMD HDA verbs specification.
Check that the latencies are valid before using them, and add a comment
describing the formats.

ALSA: hda - hdmi: Add error-checking to some codec reads
Add error checks to HBR status reads (both generic and ATI/AMD) and

Unchecked errors in these just caused more errors later on (invalid
codec writes for the HBR ones and ELD parsing errors for the ATI/AMD ELD
ones), but it is better to catch them earlier.

ALSA: usb: Fix wrong mapping of RLC and RRC channels
According to USB Audio spec v2 bits 25 and 26 of bmChannelConfig are
"Back Left of Center - BLC" and "Back Right of Center - BRC",
respectively.
They are currently assigned to ALSA channels BLC/BRC. However, the ALSA
BLC/BRC are actually the rather nonsensical "bottom left center" and
"bottom right center", so the channels will be assigned wrongly. The
comments in the USB code are also similarly wrong, so this is not
readily apparent without looking at the actual specification.
Fix the channel mapping by mapping bits 25 and 26 to RLC (Rear Left
Center) and RRC (Rear Right Center), respectively, instead.

Since the USB audio code has used the TFx positions since v3.8

The commit [8fe7b65ab465: ALSA: hda - Apply GPIO setup for MacBooks

This broke the fixups for previous MBA6,1 and 6,2, since the PCI SSID
vendor id matches before evaluating the codec SSIDs.
We had a similar issue on Mac with Sigmatel codecs, and solve this
problem again similarly, by introducing a skeleton entry matching with
the all MacBooks, then remap to the right one.

ALSA: hda - Delay HDMI presence reports while waiting for ELD information
There is a small gap between the jack detection unsolicited event and
the time the ELD is updated. When user-space queries the HDMI ELD
immediately after receiving the notification, it might fail because of
this gap.
For avoiding such a problem, this patch tries to delay the HDMI jack
detect notification until ELD information is fully updated. The
workaround is imperfect, but good enough as a starting point.
We currently assume that the DMA Slave Config will be fully populated
by the platform, however some DMA Engines make decisions based on zero
(default) flags such as DMA_SLAVE_BUSWIDTH_UNDEFINED and as this is a
static declaration we need to memset it to clear the data area.

ALSA: compress: fix drain calls blocking other compress functions (v6)
The drain and drain_notify callback were blocked by low level driver
until the draining was complete. Due to this being invoked with big
fat mutex held, others ops like reading timestamp, calling pause, drop
were blocked.
So to fix this we add a new snd_compr_drain_notify() API. This would
be required to be invoked by low level driver when drain or partial
drain has been completed by the DSP. Thus we make the drain and
partial_drain callback as non blocking and driver returns immediately
after notifying DSP. The waiting is done while releasing the lock so
that other ops can go ahead.
