From c82a0069051934e1b80e3c98b137480e548ad30d Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Tue, 13 Dec 2022 20:24:03 +0100 Subject: [PATCH] ARM: 9280/1: mm: fix warning on phys_addr_t to void pointer assignment commit a4e03921c1bb118e6718e0a3b0322a2c13ed172b upstream. zero_page is a void* pointer but memblock_alloc() returns phys_addr_t type so this generates a warning while using clang and with -Wint-error enabled that becomes and error. So let's cast the return of memblock_alloc() to (void *).
