commit 47e0bbb7fa985a0f1b5794a8653fae4f8f49de77 upstream.
request_firmware() failures currently won't get reported at all (the
error code is discarded). What's more, we get confusing messages, like:
# echo -n notafile > /sys/devices/virtual/misc/test_firmware/trigger_request
[ 8280.311856] test_firmware: loading 'notafile'
[ 8280.317042] test_firmware: load of 'notafile' failed: -2
[ 8280.322445] test_firmware: loaded: 0
# echo $?
0
Report the failures via write() errors, and don't say we "loaded"
anything.
