Back in April I created a patch to address a false-positive warning:
drivers/media/usb/rainshadow-cec/rainshadow-cec.c: In function 'rain_irq_work_handler':
drivers/media/usb/rainshadow-cec/rainshadow-cec.c:171:31: error: 'data' may be used uninitialized in this function [-Werror=maybe-uninitialized]
My patch was totally wrong and introduced a real bug, and Colin Ian King thankfully
noticed it now and fixed my mistake. Unfortunately, fixing the actual uninitialized
data in this case brought back the original bogus warning.
This is a new version of the patch, which simplifies the code to the point where
gcc notices the behavior is correct.
Fixes: ca33784ba494 ("[media] rainshadow-cec: ensure exit_loop is intialized")
Fixes: ea6a69defd3311 ("[media] rainshadow-cec: avoid -Wmaybe-uninitialized warning")
