[media] DVB-frontends: Deletion of unnecessary checks before the function call "release_firmware"
GIT_AUTHOR_DATE=1416472432
The release_firmware() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
