If write() on a VBI device node fails due to a bad buffer pointer from
userspace, we should notify the application properly with EFAULT, per the
V4L2 API spec.

ivtv_write_vbi() is used for both VBI data that came from the
driver internally and VBI data that came from the user.  However,
it did not use copy_from_user() for reading the VBI data from the
user buffers.

This change adds a new version of the function,
ivtv_write_vbi_from_user(), that uses copy_from_user() to read the VBI
data provided via user buffers.

This should resolve a sparse build warning reported by Dave Gilbert.

Hi,

release_firmware() just does nothing if passed a NULL pointer. So there's
no reason to test before the call in
saa7164-fw.c::saa7164_downloadfirmware().

Removing the pointless conditional also saves a few bytes.

'n' may be bigger than MAX_INT*sizeof(int), if so checking of truncated
(int)(n/sizeof(int)) for LIRCBUF_SIZE overflow and then using nontruncated 'count'
doesn't make sense.  Also n may be up to sizeof(int)-1 bytes bigger than expected,
so check value of (n % sizeof(int)) too.

with the device. The ALSA codec offers digital audio, without it only
analog audio is available.
