The first two patches of the series have already been merged into v7.3, while the follow-up fix (making k90_brightness_set() a no-op once removed is set) has not been merged yet. Since the original thread is about the two merged patches, I think it is cleaner to start a new thread for the remaining fix rather than appending it as a fixup to this one. I will submit the patch as a separate submission shortly, with both syzbot reports tagged so syzbot can verify the fix. Thanks again for the report. Chen Changcheng
