powerpc/perf/hv-24x7: Move cpumask file to top folder of hv-24x7 driver
Commit792f73f747
("powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show cpumask") added cpumask file as part of hv-24x7 driver inside the interface folder. The cpumask file is supposed to be in the top folder of the PMU driver in order to make hotplug work. This patch fixes that issue and creates new group 'cpumask_attr_group' to add cpumask file and make sure it added in top folder. command:# cat /sys/devices/hv_24x7/cpumask 0 Fixes:792f73f747
