Subject: [PATCH 03/10] scsi: ufs: remove version check before IS reg clear
Date: Wed, 26 Jun 2013 22:39:28 +0530 [thread overview]
Message-ID: <1372266575-3468-4-git-send-email-santoshsy@gmail.com> (raw)
In-Reply-To: <1372266575-3468-1-git-send-email-santoshsy@gmail.com>
From: Seungwon Jeon <tgih.jun@samsung.com>
There is no need to check the version to clear
the interrupt status. And the order is changed
prior to actual handling.
