Subject: scsi: esp_scsi: Always clear msg_out_len after MESSAGE OUT phase
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d60e9eec95d2e81253eaf3c39ac8baf4830d0472;p=linux.git

scsi: esp_scsi: Always clear msg_out_len after MESSAGE OUT phase

After sending a message, always clear esp->msg_out_len. Otherwise,
eh_abort_handler may subsequently fail to send an ABORT TASK SET
message.
