From d1302a36a7f1c33d1a8babc6a510e1401a5e5aed Mon Sep 17 00:00:00 2001 From: Mike Turquette Date: Thu, 29 Mar 2012 14:30:40 -0700 Subject: clk: core: copy parent_names & return error codes This patch cleans up clk_register and solves a few bugs by teaching clk_register and __clk_init to return error codes (instead of just NULL) to better align with the existing clk.h api. Along with that change this patch also introduces a new behavior whereby clk_register copies the parent_names array, thus allowing platforms to declare their parent_names arrays as __initdata.
