From ad9561609c41f704fd82facd37127e957bcaea94 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 22 Feb 2010 22:09:35 -0700 Subject: OMAP clockdomain: if no autodeps exist, don't try to add or remove them _clkdm_add_autodeps() and _clkdm_del_autodeps() will attempt to dereference a NULL pointer if no autodeps were supplied to clkdm_init(). Based on a patch from Roel Kluin - thanks Roel.
