From 1f95f8c9fddb14ec0c5b2d49f691b9c2aee7b9b9 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Fri, 23 Jan 2015 15:05:13 +0100 Subject: firewire: sbp2: remove redundant check for bidi command [Bart van Asche:] SCSI core never sets cmd->sc_data_direction to DMA_BIDIRECTIONAL; scsi_bidi_cmnd(cmd) should be used instead to test for a bidirectional command. [Christoph Hellwig:] Bidirectional commands won't ever be queued anyway, unless a LLD or transport driver sets QUEUE_FLAG_BIDI. So, simply remove the respective queuecommand check in the SBP-2 transport driver.
