I had tried that, but unless p->f is pointer of some type, we will get the warning as it is passed without a cast to __efi_rt_asm_wrapper(). > __efi_rt_asm_wrapper() was intended as a temporary thing, so I'd > prefer to avoid starting to rely on the void* type of its first > argument. > Fair enough. Can we expect p->f to be some pointer then ? If yes, then PRMT driver needs to change the handler_addr from u64 to some pointer which sounds OK to me. -- Regards, Sudeep
