From 1bf8cc3d017575a38d4361f56ccc0a670a16bcd9 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 11 Jul 2014 20:24:19 +0530 Subject: cpufreq: cpu0: OPPs can be populated at runtime OPPs can be populated statically, via DT, or added at run time with dev_pm_opp_add(). While this driver handles the first case correctly, it would fail to populate OPPs added at runtime. Because call to of_init_opp_table() would fail as there are no OPPs in DT and probe will return early. To fix this, remove error checking and call dev_pm_opp_init_cpufreq_table() unconditionally. Update bindings as well. Suggested-by: Stephen Boyd Tested-by: Stephen Boyd Signed-off-by: Viresh Kumar Acked-by: Santosh Shilimkar Signed-off-by: Rafael J.
