From fedc21dce814b500e2a9b3cc51f5f802d39e22e5 Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Mon, 15 Jul 2013 07:03:38 +0300 Subject: xtensa: fix !CONFIG_XTENSA_CALIBRATE_CCOUNT build failure Commits 925f5532 (xtensa: ccount based clockevent implementation) and e3f43291 (xtensa: ccount based sched_clock) introduced users of ccount_freq. This variable doesn't exist when CONFIG_XTENSA_CALIBRATE_CCOUNT is disabled. Add ccount_freq definition in this case.
