The 'free_irq()' call is not at the right place in the error handling path. The changed order has been introduced in commit 3d4253d9afab ("[SCSI] qlogicpti: Convert to new SBUS device framework.")
Fixes: 3d4253d9afab ("[SCSI] qlogicpti: Convert to new SBUS device framework.") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- Please review carefully. This patch is proposed because it triggers one of my coccinelle scripts. I'm not 100% sure if correct.
The script tries to spot wrongly ordered error handling path. It is: @@ identifier l1, l2; @@
