Often, "just nuke it because it's now dead code" isn't the best answer... At one time, that was likely intended to be checking whether ->dev was a null pointer, to make sure we don't pass request_firmware() a null pointer and oops the kernel, or other things that go pear-shaped.... So the question becomes: Is it safe to just remove it, or was it intended to test for something that could legitimately be null if we've hit an error along the way (which means we should fix the condition to be proper and acceptable to both gcc and clang)?
