Subject: sched/x86: Remove unnecessary TBM3 check to update topology
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=02cfdc95a0104fa5812d855d1e4ec687312aaa6f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sched/x86: Remove unnecessary TBM3 check to update topology

Scheduling to the max performance core is enabled by
default for Turbo Boost Maxt Technology 3.0 capable platforms.

Remove the useless sysctl_sched_itmt_enabled check to
update sched topology for adding the prioritized core scheduling
flag.
