From: Laurent Pinchart Date: Mon, 7 Jan 2013 01:05:19 +0000 (+0100) Subject: clk: max77686: Avoid double free at remove time X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f1ba28a1f0fa16f3d0e78d199f3f9bf13e2d487b;p=deliverable%2Flinux.git 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.
