Subject: staging: pi433: Remove SET_CHECKED usage from pi433_probe
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=54fc95a7c59612263126c2eb4d46cf674095b63c;p=linux.git

staging: pi433: Remove SET_CHECKED usage from pi433_probe

SET_CHECKED returns from the function on failure and in pi433_probe it is
necessary to free the GPIOs and the device on failure.
