Subject: arm64: topology: Skip already covered CPUs when setting freq source
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=af15bc259e260cbe5221c220d56a716b6facf155;p=thirdparty%2Fkernel%2Flinux.git

arm64: topology: Skip already covered CPUs when setting freq source

The scale freq source of the CPUs in 'amu_fie_cpus' mask are already set to
AMU tick before, so in amu_fie_setup(), only the CPUs in the 'cpus' mask
should be set.
