From b9e742c3164344fece3615aca42ec51b41753908 Mon Sep 17 00:00:00 2001 From: Tomeu Vizoso Date: Wed, 17 Sep 2014 11:34:17 +0200 Subject: [PATCH] clk: tegra: Make clock initialization more robust Don't abort clock initialization if we cannot match an entry in tegra_clk_init_table to a valid entry in the clk array. Also log a corresponding error message. This was discovered when testing a patch that removed the EMC clock from tegra124_clks but left a mention in tegra_clk_init_table.
