[PATCH] scsi: pm8001: Drop !task check in pm8001_abort_task()

From: John Garry
Date: Wed Oct 26 2022 - 06:25:38 EST


In commit 0b639decf651 ("scsi: pm8001: Modify task abort handling for SATA
task"), code was introduced to dereference "task" pointer in
pm8001_abort_task(). However there was a pre-existing later check for
"!task", which spooked the kernel test robot.

Function pm8001_abort_task() should never be passed NULL for "task"
pointer, so remove that check. Also remove the "unlikely" hint, as this is
not fastpath code.
