Browse Source 
commit 52721cfc78c76b09c66e092b52617006390ae96a upstream.

Call gpiochip_remove() to free the resources allocated by
gpiochip_add_data() in error path.

Fixes: 553b75d4bfe9 ("gpio: regmap: Allow to allocate regmap-irq device")
Fixes: ae495810cffe ("gpio: regmap: add the .fixed_direction_output configuration parameter")
