From c5e857a46af24a772f445edcc01a861ee2d6a713 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 14 Jul 2015 12:45:19 -0700 Subject: [PATCH] clk: gpio: Unlock mutex on error path We don't unlock the mutex if we fail to allocate the parent names array. Unlock it and return an error in this case as well.
