[PATCH 07/16] devfreq: Use sysfs_emit() for cpumask show callbacks
From: Yury Norov <hidden>

Also in:
driver-core, imx, linux-acpi, linux-amlogic, linux-arm-msm, linux-cxl, linux-fpga, linux-pci, linux-perf-users, linux-pm, linux-rdma, lkml, nvdimm
Subsystem:
arm/rockchip soc support, device frequency (devfreq), device frequency event (devfreq-event), the rest · Maintainers:
Heiko Stuebner, MyungJoo Ham, Kyungmin Park, Chanwoo Choi, Linus Torvalds
These callbacks are sysfs show paths. Use sysfs_emit() and cpumask_pr_args() to emit the masks. This prepares for removing cpumap_print_to_pagebuf().
