Looks there are seldom such usage patterns in kernel, so could you let me

Yes, aother way is to move 'fw_path_para' out of fw_path, and only
let fw_get_fw_file_from_paths() deal with 'fw_path_para' and
CONFIG_FW_CUSTOMIZED_PATH. Looks it is still clean.

Yes, it will be submitted as another patch, also I plan to add
the check on firmware_name in _request_firmware_prepare()
so that the similar problem can be found earlier.
