perf: arm_pmu: use DEVICE_ATTR_RO macro
Use DEVICE_ATTR_RO helper instead of plain DEVICE_ATTR, which makes the code a bit shorter and easier to read. Signed-off-by: YueHaibing <yuehaibing@huawei.com> Link: https://lore.kernel.org/r/20210528014130.7708-1-yuehaibing@huawei.com Signed-off-by: Will Deacon <will@kernel.org>
