The Kathrein RCU-676 remote uses the 32-bit rc6 protocol and toggles
bit 15 (0x8000) on repeated button presses, like MCE remotes.
Add it's customer code 0x8046 to the 32-bit rc6 toggle

If requests are not supported by the driver, then return EACCES, not
EPERM. This is consistent with the error that an invalid request_fd will

Instead of returning -ENOENT when a request_fd was not found (VIDIOC_QBUF
and VIDIOC_G/S/TRY_EXT_CTRLS), we now return -EINVAL. This is in line
with what we do when invalid dmabuf fds are passed to e.g. VIDIOC_QBUF.

Yeah, I never understood why this wasn't supported when this API was designed.
