[linux-dvb] Firmware won't load (Twinhan 7041B)

Something I just realised with the firmware loader is that you cannot 
have /lib/firmware as a symlink, because for whatever reason it does not 
follow it when looking for firmware.

(I had /lib/firmware symlinked to /usr/lib/hotplug/firmware for a long 
time and could never figure out why firmware did not load properly)

Recreating /lib/firmware as a proper directory with all the files in it 
fixed it for me.
