Subject: [PATCH 09/11] PCI: rcar: check platform_get_irq() return code
Date: Wed, 05 Feb 2014 10:19:12 +0000	[thread overview]
Message-ID: <1391595554-20640-10-git-send-email-ben.dooks@codethink.co.uk> (raw)

The current code does not check the return from platform_get_irq()
so add an error check and return if this call does fail.
