V4L/DVB (13953): firedtv: add missing NULL pointer check ...
If there is ever going to be a FireDTV or FloppyDTV firmware which does
not provide a minimal ASCII textual descriptor for Model_Id --- or if
the descriptor is provided indirectly in a descriptor directory ---
the ieee1394 variant of the device probe of firedtv would dereference a
NULL pointer. The firewire variant of firedtv's device probe is not
affected.
The fix makes sure that such an unexpected firmware is safely recognized
by fdtv_alloc as an unknown firmware.
