From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ben Dooks Date: Wed, 05 Feb 2014 10:19:12 +0000 Subject: [PATCH 09/11] PCI: rcar: check platform_get_irq() return code Message-Id: <1391595554-20640-10-git-send-email-ben.dooks@codethink.co.uk> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org The current code does not check the return from platform_get_irq() so add an error check and return if this call does fail.
