Subject: [PATCH 08/10] net: fjes: Handle return value of platform_get_irq and platform_get_resource
Date: Sun,  3 Dec 2017 00:56:20 +0530	[thread overview]
Message-ID: <1512242782-7134-9-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1512242782-7134-1-git-send-email-arvind.yadav.cs@gmail.com>

platform_get_irq() and platform_get_resource() can fail here and
we must check its return value.
