Subject: powercap / RAPL: change domain detection message
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fcdf1797e1f8f6605b194e620a333e6d47e07672;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powercap / RAPL: change domain detection message

Many CPUs do not support complete set of RAPL domains, as a
result this detection failed message is very misleading and
can be annoying.

 [    5.082632] intel_rapl: RAPL domain core detection failed
 [    5.088370] intel_rapl: RAPL domain uncore detection failed

So lower the warning message to info and only print out the RAPL
domains that are supported.
