Hmm... I'm not seeing the firmware for this driver at the
linux-firmware tree:
	https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/log/

Nor I'm seeing any pull request for them. Did you send it?
I'll only merge the driver upstream after seeing such pull request.

Regards,
Mauro

Mauro, are you confusing the decoder and encoder driver? I haven't thoroughly reviewed the decoder driver
yet, so there is no pull request for the decoder driver.

The only pull request I made was for the encoder driver.
