From mboxrd@z Thu Jan 1 00:00:00 1970 From: shawn.guo@linaro.org (Shawn Guo) Date: Thu, 5 Jul 2012 14:19:42 +0800 Subject: [PATCH] regulator: core: remove sysfs entry properly in regulator_put In-Reply-To: References: Message-ID: <1341469182-5079-1-git-send-email-shawn.guo@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org With changes introduced by commit 222cc7b (regulator: core: Allow multiple requests of a single supply mapping) on create_regulator, regulator_put needs a corresponding update on sysfs entry removing. Also regulator->dev still needs to get assigned in create_regulator, otherwise, sysfs_remove_link call in regulator_put will get bypassed.
