V4L/DVB (5315): Tda1004x: check request firmware for NULL ponter again
In older versions, this was used to decide whether to boot from eeprom or file. This is no longer necessary but the check helps to avoid an oops with misconfigured cards. Signed-off-by: Hartmut Hackmann <hartmut.hackmann@t-online.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
