Subject: [PATCH 3.4 28/35] can: flexcan: flexcan_open(): fix error path if flexcan_chip_start() fails

3.4-stable 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.
