Subject: [PATCH 3/3] mm: vmalloc: mark zero_iter() static

From: Arnd Bergmann <arnd@...db.de>

The zero_iter() function was put into the global namespace,
apparently by accident:

mm/vmalloc.c:3448:8: error: no previous prototype for function 'zero_iter' [-Werror,-Wmissing-prototypes]
size_t zero_iter(struct iov_iter *iter, size_t count)
       ^
mm/vmalloc.c:3448:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
size_t zero_iter(struct iov_iter *iter, size_t count)
^

Fixes: d9cab54f7737 ("mm: vmalloc: convert vread() to vread_iter()")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
