Subject: ARM: 9280/1: mm: fix warning on phys_addr_t to void pointer assignment
From: Giulio Benetti <giulio.benetti@xxxxxxxxxxxxxxxxxxxxxx>
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 *).
