In the case where we have both line out and more than stereo speakers,
the speaker DACs will end up in extra_out_nid.
In fact, AFAIU, speakers are the only ones that can end up in extra_out_nid,
and if we have several of those, they should be surround outputs
rather than copy front.

Currently hdmi_setup_audio_infoframe() reprograms the HDA channel
mapping only when the infoframe is not up-to-date or the non-PCM flag
has changed.
However, when just the channel map has been changed, the infoframe may
still be up-to-date and non-PCM flag may not have changed, so the new
channel map is not actually programmed into the HDA codec.
Notably, this failing case is also always triggered when the device is
already in a prepared state and a new channel map is configured while
changing only the channel positions (for example, plain
"speaker-test -c2 -m FR,FL").
Fix that by always programming the channel map in
hdmi_setup_audio_infoframe(). Tested on Intel HDMI.

On this machine, DAC on node 0x03 seems to give mono output.
Also, it needs additional patches for headset mic support.
It supports CTIA style headsets only.

The frame check in i_usX2Y_urb_complete() and
i_usX2Y_usbpcm_urb_complete() is bogus and produces false positives as
described in this LAU thread:
http://linuxaudio.org/mailarchive/lau/2013/5/20/200177
This patch removes the check code entirely.

Acer Aspire 3830TG seems requiring GPIO bit 0 as the primary mute
control. When a machine is booted after Windows 8, the GPIO pin is
turned off and it results in the silent output.
This patch adds the manual fixup of GPIO bit 0 for this model.

ASoC: Fixes for v3.12
Nothing too exciting here, all driver specific except for the fix from
Liam for DPCM systems which have both front and back end DAIs which is
not yet used by anything in mainline.

This patch avoids to dereference the uninitialized data pointer if the
error path is entered before devm_kzalloc is called (or if the allocation
fails). It fixes the following warning:

First round of IIO fixes for 3.12
A series of wrong 'struct dev' assumptions in suspend/resume callbacks
following on from this issue being identified in a new driver review.
One to watch out for in future.
A number of driver specific fixes
1) at91 - fix a overflow in clock rate computation
2) dummy - Kconfig dependency issue
3) isl29018 - uninitialized value
4) hmc5843 - measurement conversion bug introduced by recent cleanup.
5) ade7854-spi - wrong return value.
Some IIO core fixes
1) Wrong value picked up for event code creation for a modified channel
2) A null dereference on failure to initialize a buffer after no buffer has
been in use, when using the available_scan_masks approach.
3) Sampling not stopped when a device is removed. Effects forced removal
such as hot unplugging.
4) Prevent device going away if a chrdev is still open in userspace.
5) Prevent race on chardev opening and device being freed.
6) Add a missing iio_buffer_init in the call back buffer.
These last few are the first part of a set from Lars-Peter Clausen who
has been taking a closer look at our removal paths and buffer handling
than anyone has for quite some time.

Set the IIO device as the parent for the character device
We need to make sure that the IIO device is not freed while the character device
exists, otherwise the freeing of the IIO device might race against the file open
callback. Do this by setting the character device's parent to the IIO device,
this will cause the character device to grab a reference to the IIO device and
only release it once the character device itself has been removed.
Also move the registration of the character device before the registration of
the IIO device to avoid the (rather theoretical case) that the IIO device is
already freed again before we can add the character device and grab a reference
to the IIO device.
We also need to move the call to cdev_del() from iio_dev_release() to
iio_device_unregister() (where it should have been in the first place anyway) to
avoid a reference cycle. As iio_dev_release() is only called once all reference
are dropped, but the character device holds a reference to the IIO device.

The lux_uscale value is not initialized at probe. The value will be

This fixes that.

This only occurs in the unlikely event that the example driver is built
in whilst the buffer implementation is not.
Solved by switching from a depends on to a select for this particular case.

The adc_clk variable is currently defined using a 32-bits unsigned integer,
which will overflow under some very valid range of operations.
Such overflow will occur if, for example, the parent clock is set to a
20MHz frequency and the ADC startup time is larger than 215ns.
To fix this, introduce an intermediate variable holding the clock rate
in kHz.

In some circumstances, the performance of this driver is highly degraded,
and ifconfig reports large numbers of dropped packets. By increasing the
maximum RX gain from 0x3e to 0x4e, performance is greatly improved.

This warning results because the number of items in "enum rtw_c2h_event",
which determines the value of MAX_C2HEVT, is one more than in "struct wlanevents".
Adding an extra dummy event to the latter fixes the problem.

mips allmodconfig fails with
ERROR: "copy_from_user_page" [drivers/staging/lustre/lustre/libcfs/libcfs.ko]

which is due to LUSTRE using copy_from_user_page which is not exported by any
architecture. Unfortunately, LUSTRE can only be built as module, so there is no
easy fix.
MIPS, SH, and optionally XTENSA implement copy_from_user_page as unexported
functions. Disable LUSTRE for those.

It's incorrect, Kay writes:
Please just remove it. "devname" is meant to be used for
single-instance devices with a static dev_t, never for things
like zramX.
It will not do anything useful here, it does nothing really
without a statically assigned dev_t, and it should not be used
for devices of this kind anyway.

Enable only those interrupts that we can handle & acknowledge in the
interrupt handler.
At least on EdgeRouter Lite, the hardware may occasionally interrupt with
some error condition when the physical link status changes frequently.
Since the interrupt condition is not acked properly, this leads to the
following warning and the IRQ gets disabled completely:
