This patch implements the basic data types for the standard channel
mapping API handling.
- The definitions of the channel positions and the new TLV types are
added in sound/asound.h and sound/tlv.h, so that they can be
referred from user-space.
- Introduced a new helper function snd_pcm_add_chmap_ctls() to create
control elements representing the channel maps for each PCM
(sub)stream.
- Some standard pre-defined channel maps are provided for
convenience.

Recently the check for non-PCM stream state was added to the generic
HDMI driver code. But this check should be done rather to each pin
instead of each converter. Otherwise when a different converter is
assigned at the next open, the audio infoframe can be inconsistent
with the setup using the previous converter.
For fixing this issue, this patch moves the state of the current
non-PCM status from per_cvt to per_pin. (In addition an unused
argument cvt_nid is stripped from hdmi_setup_channel_mapping())

__ieee80211_key_destroy() calls synchronize_rcu() in

However, synching the tx path can be done with

Pass the checks made by decode_getacl back to __nfs4_get_acl_uncached
so that it knows if the acl has been truncated.
The current overflow checking is broken, resulting in Oopses on
user-triggered nfs4_getfacl calls, and is opaque to the point
where several attempts at fixing it have failed.
This patch tries to clean up the code in addition to fixing the
Oopses by ensuring that the overflow checks are performed in
a single place (decode_getacl). If the overflow check failed,
we will still be able to report the acl length, but at least
we will no longer attempt to cache the acl or copy the
truncated contents to user space.

Add support for the O_DIRECT flag. There are two cases to deal with:
1. Small files stored in the ICB (inode control block?): just return 0
from the new udf_adinicb_direct_IO() handler to fall back to buffered
I/O.
2. Larger files, not stored in the ICB: nothing special here. Just call
blockdev_direct_IO() from our new udf_direct_IO() handler and tidy up
any blocks instantiated outside i_size on error. This is pretty
standard. Factor error handling code out of udf_write_begin() into new
function udf_write_failed() so it can also be called by udf_direct_IO().
Also change the whitespace in udf_aops to make it a bit neater.

The recent fix for the missing fine delayed time adjustment gives
strange error messages at each start of the playback stream, such as
delay: estimated 0, actual 352
delay: estimated 353, actual 705
These come from the sanity check in retire_playback_urb(). Before the
stream is activated via start_endpoints(), a few silent packets have
been already sent. And at this point the delay account is still in
the state as if the new packets are just queued, so the driver gets
confused and spews the bogus error messages.
For fixing the issue, we just need to check whether the received
packet is valid, whether it's zero sized or not.

When booted with some resource will have their name set to NULL. This can
cause later kernel crash since this is not expected by the platform code.
When we boot without DT the devices are created with platform_device_add()
which itself fixes up the missing resource names:
if (r->name == NULL)
r->name = dev_name(&pdev->dev);
The of core also fixes up the resource names when taking the information
from DT data - in __of_address_to_resource():
r->name = name ? name : dev->full_name;
When we boot OMAP with devicetree: of will create the devices based on the
DT data so the resource names are guarantied to be not NULL. Since we have
the 'ti,hwmod' tag, we remove the of created resources from the device and
re-create them based on hwmod data. If the hwmod data does not specify a
name for a resource it will be NULL.
This can cause kernel crash if the driver uses
platform_get_resource_byname() to get any resource.

The pause and resume operations indicate that the stream can be
un-paused/resumed from the exact location they were paused/suspended.
This is not true for this driver, the pause and suspend triggers share
the same code path with stop, they flush all pending DMA transfers.
This drops all pending samples. The pause_release/resume triggers are
the same as start, except that prepare won't be called beforehand,
nothing will be enqueued to the DMA engine and nothing will happen (no
audio). Removing the pause flag will let apps know that it isn't
supported. Removing the resume flag will cause user space to call
prepare and start instead of resume, so audio will continue playing when
the system wakes up.
Before removing the pause and resume flags, I tested this on an exynos
5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a
write error. Suspend/resume testing led to the same result. Removing
the two flags fixes suspend/resume (since snd_pcm_prepare is called
again). And leads to a proper reporting of pause not supported.

If the subchannel event function is called from IRQ context and we

However if the subchannel reappeared at the time the event function
gets called from process context we would do nothing and leave the
device in not operational state. Recognize this case in sch_get_action
