Date: Mon, 7 Jan 2013 02:05:19 +0100 From: Laurent Pinchart <laurent.pinchart@...asonboard.com> To: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: Jonghwa Lee <jonghwa3.lee@...sung.com>, Mike Turquette <mturquette@...aro.org> Subject: [PATCH] clk: max77686: Avoid double free at remove time The clk_lookup entry is dropped at remove time by a call to clkdev_drop(). That function frees the entry, which is also freed by the driver core as it has been allocated through devm_kzalloc(). This results in a double free. Use kzalloc() instead of devm_kzalloc() to fix this.
