From d51546c0db975a4750161d17eef62dfcf9eedc90 Mon Sep 17 00:00:00 2001 From: Niklas Söderlund Date: Wed, 29 Mar 2017 20:43:52 +0200 Subject: thermal: rcar_gen3_thermal: check that TSC exists before memory allocation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the check for a TSC resource before allocating memory for a new TSC. If no TSC is found there is little point in allocating memory for it.
