Subject: [PATCH 2/4] usb-storage: do not increment cmd->serial_number
Date: Mon, 4 Apr 2011 09:42:22 -0400 [thread overview]
Message-ID: <20110404134221.GB32522@infradead.org> (raw)
In-Reply-To: <20110404134203.GA29525@infradead.org>
The isd200 sub-driver increments the command serial number despite not
using it at all in it's routine for sending internal scsi commands.
Remove the increment to prepare for removing the serial_number field.
