I'm an idiot. The context ID can be a really large unsigned number, which
means it'll appear negative as an int. So actually the right fix here is just
to set it regardless of the returned value (but only for this particular

This reverts commit eccf2979b2.
The reason is that it broke TI WiLink shared transport on Panda.
Also, callback functions should not be added to board files anymore,
so revert to implementing the power functions in the driver itself.
Additionally, changed a variable name ('status' to 'err') so that this
revert compiles properly.

$ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data
$ echo 0 > /sys/class/firmware/spi0.0/loading

When st driver decodes protocol index received from raw data,
it does a value convert from "char" to "int". Because it's sign
extension from bit8 to bit32, the "int" value maybe minus, in
another word, the protocol index might be minus, but driver doesn't
filter such case and may continue access memory pointed by this
minus index.
This patch is to change the variable type of index from "int"
to "unsigned char", so that it avoids do such kind of type
conversion.

The rest are a few fixes for M-Audio usb-audio device and a fix for
regression of HD-audio HDMI codecs with alsactl in the recent kernel.
