You should just set 'cpumask' to cpumask of cpu_dev->id at the top of the function.

Don't skip cpu_dev->id when setting up cpumask for CPUs that share the same OPP table. This might be helpful when handling cpumask without the original CPU bitfield set. Signed-off-by: Pi-Cheng Chen <pi-cheng.chen@linaro.org> --- drivers/base/power/opp/cpu.c | 4 ---- 1 file changed, 4 deletions(-)
