4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ricardo Ribalda Delgado <ricardo.ribalda@xxxxxxxxx> commit 19a4fbffc94e41abaa2a623a25ce2641d69eccf0 upstream. The current code only frees N-1 gpios if an error occurs during gpiod_set_transitory, gpiod_direction_output or gpiod_direction_input. Leading to gpios that cannot be used by userspace nor other drivers.
