dnl # firmware loader: inform direct failure when udev loader is disabled
dnl # Now that the udev firmware loader is optional request_firmware()
dnl # will not provide any information on the kernel ring buffer if
dnl # direct firmware loading failed and udev firmware loading is disabled.
dnl # If no information is needed request_firmware_direct() should be used
dnl # for optional firmware, at which point drivers can take on the onus
dnl # over informing of any failures, if udev firmware loading is disabled
dnl # though we should at the very least provide some sort of information
dnl # as when the udev loader was enabled by default back in the days.
