Subject: [PATCH 3/8] staging: et131x: Use for loop to initialise contiguous registers to zero
Date: Wed, 20 Aug 2014 23:17:53 +0100	[thread overview]
Message-ID: <1408573078-9320-4-git-send-email-mark.einon@gmail.com> (raw)
In-Reply-To: <1408573078-9320-1-git-send-email-mark.einon@gmail.com>

Replace a long list of contiguous writel() calls with a for loop iterating
over the same values.
