From ef22d576dd9d028dba53476bbcfc36aa1b5d768b Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 26 Aug 2013 12:04:05 +0800 Subject: [PATCH] vme: vme_ca91cx42.c: fix to pass correct device identity to free_irq() free_irq() expects the same device identity that was passed to corresponding request_irq(), otherwise the IRQ is not freed.
