From d73ac4ca66676d0b0d57a8828d10d479ad054d0c Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Thu, 12 Dec 2013 17:07:18 +0100 Subject: clk: max77686: Fix clean-up in error and remove paths This patch fixes invalid kfree() and adds missing call to clk_unregister() in error and remove paths in max77686_clk_probe(). While at it, error handling is also cleaned up.
