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
hypercall; normally we would check it).

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.

vmci_send_datagram() returns an int, with negative values indicating failure.
But we store it locally in a u32, which makes comparison of >= 0 useless.

This patch adds support for bitstream configuration (programming /
loading) of the Lattice ECP3 FPGA's via the SPI bus.
Here an example on my custom MPC5200 based board:
$ echo 1 > /sys/class/firmware/spi0.0/loading
$ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data
$ echo 0 > /sys/class/firmware/spi0.0/loading
leads to these messages:
lattice-ecp3 spi0.0: FPGA Lattice ECP3-35 detected
lattice-ecp3 spi0.0: Configuring the FPGA...
lattice-ecp3 spi0.0: FPGA succesfully configured!

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.

Pull second round of sound fixes from Takashi Iwai:
"Yet a few more fixes popped up in this week.
The biggest change here is the addition of pinctrl support for Atmel,
which turned out to be almost mandatory to make things working.
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."
