From d7a56b7bdf1ea34194fe86639cc318d7a33b9abb Mon Sep 17 00:00:00 2001
From: Parth Gajjar <parth.gajjar@xilinx.com>

Subject: [PATCH] Fix gpu driver probe failure
In patch a1a2b7125e1079cfcc13a116aa3af3df2f9e002b
(Drop static setup of IRQ resource from DT core) platform_get_resource()
stopped from returning the IRQ, as all drivers were supposed to have
switched to platform_get_irq().
Using platform_get_irq_optional() to avoid printing error messages
for interrupts not found.
