Apply const prefix to the static table for registers.
Just for minor optimization and no functional changes.

Most of snd_kcontrol_new definitions are read-only and passed as-is.
Let's declare them as const for further optimization.There should be no functional changes by this patch.

Now we may declare const for snd_device_ops definitions, so let's do
it for optimization.There should be no functional changes by this patch.

Since commit 49af54ff0fc7 ("misc: atmel-ssc: prepare clock only when

This updates the at73c213 driver to enable the SSC clock whenever it is

Treat both negative and zero return values from clk_round_rate()
as errors. This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather
than a signed type, since some clock sources can generate rates higher
than (2^31)-1 Hz.Eventually, when calling clk_round_rate(), only a return value of
zero will be considered a error. All other values will be
considered valid rates. The comparison against values less than
0 is kept to preserve the correct behavior in the meantime.Signed-off-by: Paul Walmsley

This header file exists only for some hacks to adapt alsa-driver
tree. It's useless for building in the kernel. Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it. This should be really killed in
future.Signed-off-by: Takashi Iwai

This patch fixes the locking bug in the at73c213 SPI sound driver. This bug was
triggered because spinlocks were wrapped around the spi_sync call which might
sleep. The fix was to add a mutex to the sound driver and replace the spinlocks
in the mixer functions with mutex lock/unlock.

This patch adds support for the AT73C213 DAC using the misc Atmel SSC driver in
I2S mode. The driver also requires a SPI to setup the registers and control
volume.
It has been tested with an AT32AP7000 on the ATSTK1000 development board. The
driver should also work with any Atmel device with an SSC module supported by
the Atmel SSC driver (atmel-ssc).
The atmel-ssc driver is just submitted to the Linux kernel. Please see mail
