Now that the udev firmware loader is optional request_firmware() will not provide any information on the kernel ring buffer if direct firmware loading failed and udev firmware loading is disabled. If no information is needed request_firmware_direct() should be used for optional firmware, at which point drivers can take on the onus over informing of any failures, if udev firmware loading is disabled though we should at the very least provide some sort of information as when the udev loader was enabled by default back in the days. With this change with a simple firmware load test module [0]: Example output without FW_LOADER_USER_HELPER_FALLBACK platform fake-dev.0: Direct firmware load for fake.bin failed with error -2 Example with FW_LOADER_USER_HELPER_FALLBACK platform fake-dev.0: Direct firmware load for fake.bin failed with error -2 platform fake-dev.0: Falling back to user helper Without this change without FW_LOADER_USER_HELPER_FALLBACK we get no output logged upon failure.
