Subject: [PATCH] regmap: Devices using format_write don't support bulk operations
Date: Mon, 30 Apr 2012 23:27:26 +0100 [thread overview]
Message-ID: <1335824846-22136-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
Set the use_single_rw flag for devices that use format_write() since
format_write() doesn't support any form of block operation.
