TBH I think there's not alot of value in supporting a broken firmware 
which only does decode.

There's not alot of value to the user in that configuration.

Provided you have done the work to get the fixed firmware into 
linux-firmware just cut at that point and have the driver reject lesser 
versions.

I as a user have no use-case or value in a broken old firmware which 
supports decode only, I'd much rather have the full transcoder.

Its Vikash/Dikshita's call though.
