Subject: can: flexcan: flexcan_open(): fix error path if flexcan_chip_start() fails
From: Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>
commit 7e9e148af01ef388efb6e2490805970be4622792 upstream.
If flexcan_chip_start() in flexcan_open() fails, the interrupt is not freed,
this patch adds the missing cleanup.
