Subject: [PATCH 3.2 156/200] can: flexcan: flexcan_open(): fix error path
if flexcan_chip_start() fails
3.2.56-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Marc Kleine-Budde <mkl@...gutronix.de>
commit 7e9e148af01ef388efb6e2490805970be4622792 upstream.
If flexcan_chip_start() in flexcan_open() fails, the interrupt is not freed,
this patch adds the missing cleanup.
