Do not call dev_warn with a NULL device, this silence the following 2
warnings:
[ 14.392194] (NULL device *): Failed to find gmin variable gmin_V2P8GPIO
[ 14.392257] (NULL device *): Failed to find gmin variable gmin_V1P8GPIO
We could switch to using pr_warn for dev == NULL instead, but as comments
in the source indicate, the check for these 2 special gmin variables with
a NULL device is a workaround for 2 specific evaluation boards, so
completely silencing the missing warning for these actually is a good
thing.

efivar_entry_get has certain alignment requirements and the atomisp
platform code was not honoring these, causing an oops by triggering the
WARN_ON in arch/x86/platform/efi/efi_64.c: virt_to_phys_or_null_size().
This commit fixes this by using the members of the efivar struct embedded
in the efivar_entry struct we kzalloc as arguments to efivar_entry_get(),
which is how all the other callers of efivar_entry_get() do this.

Capture driver silently overrides pixel format with a hack (according to
the comments) to pass v4l2 compliance tests. This isn't needed for
normal functionality, and works for composite video and raw camera capture
without.
In addition, the hack assumes that it only supports raw capture with a
single format (SBGGR8) which isn't true. VPIF can also capture 10- and
12-bit raw formats as well. Forthcoming patches will enable VPIF
input with raw-camera support and has been tested with 10-bit format
from the aptina,mt9v032 sensor.
Any compliance failures should be fixed with a real fix.

The ir-spi driver has 2 issues which prevents it from working with
lirc:
1. The ir-spi driver uses 16 bits of SPI data to create one cycle of
the waveform. As such our SPI clock needs to be 16x faster than the
carrier frequency.
The driver is inconsistent in how it currently handles this. It
initializes it to the carrier frequency:
But the commit message has some example code which initialises it
to 16x the carrier frequency:
val = 608000;
ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val);
To maintain compatibility with lirc, always do the frequency adjustment
in the driver.
2. lirc presents pulses in microseconds, but the ir-spi driver treats
them as cycles of the carrier. Similar to other lirc drivers, do the
conversion with DIV_ROUND_CLOSEST().
