Subject: [PATCH 81/84] staging: unisys: visorhba: Call scsi_done() directly
Date: Tue, 21 Sep 2021 10:34:33 -0700	[thread overview]
Message-ID: <20210921173436.3533078-3-bvanassche@acm.org> (raw)
In-Reply-To: <20210921173436.3533078-1-bvanassche@acm.org>

Conditional statements are faster than indirect calls. Hence call
scsi_done() directly.
