From 3eef38a14370c673134600130094472e2c3f4041 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 14 Jul 2020 18:03:01 +0200 Subject: [PATCH] scsi: aic79xx: Restore modes when exiting ahd_linux_queue_abort_cmd() ahd_linux_queue_abort_cmd() calls ahd_save_modes() without calling ahd_restore_modes() before exiting.
