From 353efd5e97a7973d78f2634274b57309d0966e29 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Tue, 28 Jun 2022 13:53:43 +0100 Subject: [PATCH] ACPI: PRM: Change handler_addr type to void pointer handler_addr is a virtual address passed to efi_call_virt_pointer. While x86 currently type cast it into the pointer in it's arch specific arch_efi_call_virt() implementation, ARM64 is restrictive for right reasons. Convert the handler_addr type from u64 to void pointer. Signed-off-by: Sudeep Holla Acked-by: Rafael J.
