These three patches go to different subsystems so hopefully the
individual maintainers can apply them.  I can resend them as
individual patches if that's easier.

The ihex firmware code is a list of records of various lengths.  The
ihex code ensures that total length of the records doesn't read
beyond the end of the fw->data[], however the parsers need to check
that individual records are not too large.

  media: gspca: Add bounds checking to firmware parser
  watchdog: ziirave_wdt: check record length in ziirave_firm_verify()
  Input: ims-pcu - Check record size in ims_pcu_flash_firmware()
