OK, I got it, thank you for sharing the use case. If loading directly, the patch isn't needed because filp_open() can return failure on non-existent file. If loading via user space, timeout or not depends on userspace, at least udev won't timeout on non-existent firmware image. Also looks request_firmware_nowait() is better for the case, _nowait() can avoid unnecessary delay and speedup firmware loading if there are more than one firmware to load.
