Date: Fri, 7 Sep 2012 11:01:20 +0800 From: Mark Brown <broonie@...nsource.wolfsonmicro.com> To: Liam Girdwood <lrg@...com> Cc: linux-kernel@...r.kernel.org, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [PATCH] regulator: core: Fast path non-deferred disables Users (especially framework code) may end up passing in a zero deferral time depending on runtime conditions or configuration. If they do then just call regulator_disable() directly to save scheduling.
