Subject: perf: Remove perf_event_attr::type check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9985c20f9e4aee6857c08246b273a3695a52b929;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

perf: Remove perf_event_attr::type check

PMU type id can be allocated dynamically, so perf_event_attr::type check
when copying attribute from userspace to kernel is not valid.
