Subject: gpio: rcar: NULL dereference on error in probe()
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 0c8aab8e65e450f2bfea494c1b6a86ded653f88c upstream.
It's not obvious from the label name but "err1" tries to release
"p->irq_domain" which leads to a NULL dereference.
Fixes: 119f5e448d32 ('gpio: Renesas R-Car GPIO driver V3')
