of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. So mark the only non-const struct in arch/arm64 as const, too. Signed-off-by: Uwe Kleine-K?nig <redacted> --- arch/arm64/kernel/perf_event.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
