From 7892158a96629c46c46dfae52eaf951f51222cf5 Mon Sep 17 00:00:00 2001 From: David Riley Date: Wed, 18 Mar 2015 10:52:25 +0100 Subject: soc/tegra: pmc: move to using a restart handler The pmc driver was previously exporting tegra_pmc_restart, which was assigned to machine_desc.init_machine, taking precedence over the restart handlers registered through register_restart_handler().
