Message-Id: <1336390862-22479-1-git-send-email-broonie@opensource.wolfsonmicro.com> Date: Mon, 7 May 2012 12:41:02 +0100 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: 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().
