[PATCH] ARM: mm: fix warning on phys_addr_t to void pointer assignment

From: Giulio Benetti
Date: Tue Dec 13 2022 - 14:19:10 EST


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 *).
