From 070b9079226d4f3e3e7c9f4eb81f2e02e7d99572 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 16 Jan 2012 19:39:58 -0800 Subject: regulator: Add devm_regulator_get() Add a resource managed regulator_get() to simplify regulator usage in drivers. This allows driver authors to "get and forget" about their regulators by automatically calling regulator_put() when the driver is detached.
