perf/x86/intel/lbr: Use setup_clear_cpu_cap() instead of clear_cpu_cap()
Browse files Browse the repository at this point in the history
[ Upstream commit b329f5d ]

clear_cpu_cap(&boot_cpu_data) is very similar to setup_clear_cpu_cap()
except that the latter also sets a bit in 'cpu_caps_cleared' which
later clears the same cap in secondary cpus, which is likely what is
meant here.
