From 2b5a24a01df12fbfa3e702ad7efae27bcb852e33 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 7 Sep 2012 11:00:53 +0800 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.
