Subject: [PATCH 4/8] pinctrl: ralink: rt2880: add missing NULL check
Date: Sun, 13 Dec 2020 17:17:17 +0100	[thread overview]
Message-ID: <20201213161721.6514-5-sergio.paracuellos@gmail.com> (raw)
In-Reply-To: <20201213161721.6514-1-sergio.paracuellos@gmail.com>

Memory is being requested to the kernel but there is
a missing check for NULL. Hence, add it.
