Subject: [PATCH] media: siano: Simplify smscore_load_firmware_from_file
The function is never called with a loadfirmware_handler, so we can
remove some dead code.
We can also use this as a excuse to remove some unused type definitions.
This fixes the following smatch warning:
drivers/media/common/siano/smscoreapi.c:1172 smscore_load_firmware_from_file() error: we previously assumed 'loadfirmware_handler' could be null (see line 1150)
