Takashi Iwai b4e5e70775 ALSA: pci: Constify snd_kcontrol_new items
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.

Takashi Iwai 57a4451d26 ALSA: Use strlcpy() instead of strncpy()

one, strlcpy().

Bill Pemberton e23e7a1436 ALSA: pci: remove __dev* attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Andres Salomon 3c55494670 ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimization
Previously, OLPC support for the mic extensions was only enabled in the
ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set.  This was
because the old geode GPIO code was written in a manner that assumed
CONFIG_MGEODE_LX.  With the new cs553x-gpio driver, this is no longer the
case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead
include a requirement on GPIOLIB.

We use the generic GPIO API rather than the cs553x-specific API.

Always turn off mic bias; the MIC LED should never come on when the
driver is first loaded.

Andres Salomon bf1e527835 ALSA: cs5535audio: rename V_REFOUT control to MIC Bias
This drops the AD1888 V_REFOUT control, and replaces it with a MIC Bias
Enable control.  It also moves the MIC bias enabling into a separate
function.

Andres Salomon 189d34e747 ALSA: cs5535audio: check OLPC's Analog Input status vis GPIO
Checking the HPF register is irrelevant; HPF is secondary to the AI mode.
Instead, check for Analog Input mode via GPIO.

Andres Salomon 466ae3055b ALSA: cs5535audio: rename OLPC's analog input control && drop AD1888's HPF
Previously, we had two separate controls; there's no need to have AD1888's
HPF control, so drop it if we're on an OLPC machine.  Also, as per Arjun's
request, rename OLPC's Analog Input Switch control to "DC Mode Enable".
