From 596f482a90ae27ea1b3da6a12ee42909045fbfd0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 2 Jan 2007 12:56:00 +0100 Subject: [PATCH] [SCSI] kill scsi_rety_command scsi_retry_command only has a single caller, so there is no point in having this function. Additionally the memset of the sense buffer it does is entirely superflous as scsi_request_fn already calls scsi_init_cmd_errh to perform this memset before the command is reissued.
