Subject: [PATCH 05/14] lib: devmem_is_allowed: include linux/io.h

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

The devmem_is_allowed() function is defined in a file of the same name,
but the declaration is in asm/io.h, which is not included there, causing
a W=1 warning:

lib/devmem_is_allowed.c:20:5: error: no previous prototype for 'devmem_is_allowed' [-Werror=missing-prototypes]

Include the appropriate header to avoid the warning.
