Patch introduces new amradio_set_mute function. Amradio_start and
amradio_stop removed. This makes driver more flexible and it's useful
for next changes.

Move radio->muted and radio->stereo in section where radio mutex is
locked to avoid possible race condition problems or access to memory.
Thanks to David Ellingsworth <david@identd.dyndns.org> for pointing to
this weak place in driver.

From: Hans Verkuil <hverkuil@xs4all.nl>
Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

Because this device doesn't provide any powermanagment capabilities(may
be they exist but unknown to me yet, so they are not implemented), we
should turn them off. Patch sets support_autosuspend equal to 0.

This patch fixes problems(kernel oopses) with unplug of device while
it's working.
Patch adds disconnect_lock mutex, changes usb_amradio_close and
usb_amradio_disconnect functions and adds a lot of safety checks.

drivers/media/radio/radio-mr800.c, and place dev_warn, dev_info in right
places.
Printk changed on pr_info and pr_err macro. Also new macro
amradio_dev_warn defined. Name in usb driver struct changed on
MR800_DRIVER_NAME.

This patch creates a new usb-radio driver, radio-mr800.c, that
supports the AverMedia MR 800 USB FM radio devices.
This device plugs into both the USB and an analog audio input, so this
thing only deals with initialization and frequency setting, the audio
data has to be handled by a sound driver.
