Correct, this needs to be fixed in platform_profile_register() too, both in drivers/acpi/platform_profile.c and in include/linux/platform_profile.h Otherwise we will get a compiler warning (or maybe even an error) about assigning a pointer pointing to const memory to a pointer not pointing to const mem.

All planned uses of cur_profile have their platform_profile_handler defined as const, so just drop const qualifier here to prevent build error.
