Subject: [PATCH v3 07/13] scsi: ufs: add specific callback for nexus type
Date: Thu, 01 Oct 2015 13:39:24 +0530 [thread overview]
Message-ID: <1443686970-28104-8-git-send-email-alim.akhtar@samsung.com> (raw)
In-Reply-To: <1443686970-28104-1-git-send-email-alim.akhtar@samsung.com>
From: Seungwon Jeon <essuuj@gmail.com>
Some host controller needs nexus type information for handling
command. This change adds specific callback function to support
vendor's implementation.
