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")
