Subject[PATCH] ARM: mm: fix warning on phys_addr_t to void pointer assignment
Date
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 *).

Cc: <stable@vger.kernel.org> # 4.14.x +
Fixes: 340a982825f7 ("ARM: 9266/1: mm: fix no-MMU ZERO_PAGE() implementation")
