Subject[RFT 3/7] firmware: make fw_add_devm_name() return 0 if cache present
Date
Currently fw_add_devm_name() returns 1 if the firmware cache
was already set. This makes it complicated for us to check for
correctness. It is actually non-fatal if the firmware cache
is already setup, so just return 0, and simplify the checkers.
