From f79b5d8abf4c37f689eca5c18a5185db5f6cdb9d Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Tue, 24 Apr 2012 16:05:32 +0200 Subject: [PATCH] ARM: OMAP3: cpuidle - remove the 'valid' field With the previous changes all the states are valid, except the last state which is now handled at runtime by next_valid_state() based on the errata flags.
