Subject: [PATCH 11/12] gpio: mxs: use devm_irq_alloc_descs()
Date: Sat,  4 Mar 2017 17:23:39 +0100	[thread overview]
Message-ID: <1488644620-11488-12-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1488644620-11488-1-git-send-email-bgolaszewski@baylibre.com>

This driver never frees the interrupt descriptors it allocates. Fix
it by using the resource managed version of irq_alloc_descs().
