gpio: sysfs: fix memory leak in gpiod_sysfs_set_active_low
commit 49d2ca84e433dab854c7a866bc6add09cfab682d upstream. Fix memory leak in the gpio sysfs interface due to failure to drop reference to device returned by class_find_device when setting the gpio-line polarity. Fixes: 0769746183ca ("gpiolib: add support for changing value polarity in sysfs") Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
