Date: Wed, 21 Dec 2011 10:48:02 -0500 From: Michael Williamson <michael.williamson@...ticallink.com> To: linux-kernel@...r.kernel.org Cc: Michael Williamson <michael.williamson@...ticallink.com>, broonie@...nsource.wolfsonmicro.com, gregkh@...e.de Subject: [PATCH] regmap: fix return value in regcache-indexed read call. The regcache_read() API for regmap requires a 0 return value for successful cached reads. The read method for the indexed type cache implementation is returning the positive map offset for a successful read, which is incorrect. Fix it.
