617ade61ea [media] radio drivers: in non-blocking mode return EAGAIN in hwseek
VIDIOC_S_HW_FREQ_SEEK should return EAGAIN when called in non-blocking
mode. This might change in the future if we add support for this in the
future, but right now this is not supported.

ec6f432810 [media] v4l2: make vidioc_s_freq_hw_seek const
Write-only ioctls should have a const argument in the ioctl op.
Do this conversion for vidioc_s_freq_hw_seek.
Adding const for write-only ioctls was decided during the 2012 Media Workshop.

d7aab0bf9d [media] radio-tea5777: Add support for tuning AM
This completes my work on the Griffin radioSHARK2 driver, let me use this
opportunity to thank Hisaaki Shibata for his generous donation of a
Griffin radioSHARK2 to me, which has made this driver possible.

4fad5c474f [media] radio-tea5777.c: Get rid of do_div usage
freq fits easily into 32 bits until it gets shifted, so make it 32 bits,
and cast it to 64 bits before shifting.

[mchehab@redhat.com: also remove asm/div64.h header, as this is not
 needed anymore]

4faba767c6 [media] shark2: New driver for the Griffin radioSHARK v2 USB radio receiver
This driver consists of 2 parts, a generic tea5777 driver and a driver
for the Griffin radioSHARK v2 USB radio receiver, which is the only driver
using the generic tea5777 for now.

This first version only implements FM support, once the the new
VIDIOC_ENUM_FREQ_BANDS API is upstream I'll also add AM support.
