From 8514b5439c90f077fadaf981b5f1aec9cde7be76 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Sat, 4 Mar 2017 17:23:39 +0100 Subject: [PATCH] gpio: mxs: use devm_irq_alloc_descs() This driver never frees the interrupt descriptors it allocates. Fix it by using the resource managed version of irq_alloc_descs().
