From: Bart Van Assche Date: Thu, 7 Oct 2021 20:46:11 +0000 (-0700) Subject: scsi: core: Call scsi_done directly X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=11b68e36b16752ae3a48dc16229958ebc9bb324a;p=linux.git scsi: core: Call scsi_done directly Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Since this patch removes the last user of the scsi_done member, also remove that data structure member.
