From 41ec66c92299889ad30871aeede89b960f08a458 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 17 Jun 2015 20:59:42 +0900 Subject: gpio: altera: use of_mm_gpiochip_remove() to fix memory leak This driver calls of_mm_gpiochip_add() to add a memory mapped gpio chip. So, of_mm_gpiochip_remove() should be used when removing it. The direct call of gpiochip_remove() misses unmapping the register and freeing the label.
