Takashi Iwai 57a4451d26 ALSA: Use strlcpy() instead of strncpy()
We tend to make stupid mistakes with strncpy().  Let's take a safer
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.

Andres Salomon c8f0eeebc1 ALSA: cs5535audio: turn off mic bias on OLPCs by default
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".

Andres Salomon 1e2232bc70 ALSA: cs5535audio: decouple HPF from V_REFOUT in OLPC code
We shouldn't be touching V_REFOUT when we toggle HPF/analog input, so just
drop that code.
