From: Baruch Siach Date: Mon, 15 Jul 2013 04:03:38 +0000 (+0300) Subject: xtensa: fix !CONFIG_XTENSA_CALIBRATE_CCOUNT build failure X-Git-Tag: v3.12-rc1~15^2~2 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=fedc21dce814b500e2a9b3cc51f5f802d39e22e5;p=linux.git 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.
