Because this is dev_dbg() I'm willing to consider it, so that its not
always enabled. However its not in the right place, the code path you
are addressing is only for direct filesystem lookups. If that fails
some systems do a fallback call out to userspace. To cover both cases,
you want it at the end of _request_firmware() on the success path. Can
you send a new patch?
