From: Viresh Kumar Date: Tue, 15 Apr 2014 05:24:37 +0000 (+0530) Subject: tick-common: Fix wrong check in tick_check_replacement() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=521c42990e9d561ed5ed9f501f07639d0512b3c9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git tick-common: Fix wrong check in tick_check_replacement() tick_check_replacement() returns if a replacement of clock_event_device is possible or not. It does this as the first check: if (tick_check_percpu(curdev, newdev, smp_processor_id())) return false; Thats wrong. tick_check_percpu() returns true when the device is useable. Check for false instead.
