Date: Wed, 28 Sep 2011 11:43:42 +0100 From: Dimitris Papastamos <dp@...nsource.wolfsonmicro.com> To: Mark Brown <broonie@...nsource.wolfsonmicro.com> Cc: linux-kernel@...r.kernel.org, Lars-Peter Clausen <lars@...afoo.de> Subject: [PATCH 2/7] regmap: Modify map->cache_bypass directly In preperation for the upcoming patches, modify map->cache_bypass directly. The helper functions will grab an exclusive lock. Because we'll have acquired the same lock we need to avoid a deadlock.
