From 968c2c1707a3396ccd6e7e6c5ddaf658a6d3bd66 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 7 May 2012 11:34:52 +0100 Subject: regulator: Actually free the regulator in devm_regulator_put() It turns out that (quite surprisingly) devres_destroy() only undoes the devres mapping, it doesn't destroy the underlying resource, meaning that anything using devm_regulator_put() would leak. While we wait for the new devres_release() which does what we want to get merged open code it in devm_regulator_put().
