From 947355850fcb3bb6549294316667d0f53bc03082 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Thu, 1 Dec 2016 16:28:20 +0530 Subject: PM / OPP: Separate out _generic_set_opp() Later patches would add support for custom set_opp() callbacks. This patch separates out the code for _generic_set_opp() handler in order to prepare for that. Signed-off-by: Viresh Kumar Tested-by: Dave Gerlach Reviewed-by: Stephen Boyd Signed-off-by: Rafael J.
