[PATCH 1/2] [media] c8sectpfe: initialize err in load_slim_core_fw

[Nicolas Iooss]

load_slim_core_fw() uses a for loop with !err in its condition without
first initializing err.  Fix this by setting err to 0 in its definition.

[PATCH 2/2] [media] c8sectpfe: forward err instead of returning an uninitialized variable

[Nicolas Iooss]

When load_c8sectpfe_fw_step1() tests whether the return value of
request_firmware_nowait(), stored in variable err, indicates an error,
it then returns the value hold by uninitialized variable ret, which
seems incorrect.

Fix this by forwarding the error returned by request_firmware_nowait()
to the caller of load_c8sectpfe_fw_step1().
