staging: vchiq_arm: mark vchiq_platform_init() static
This function has no callers from other files, and the declaration
was removed a while ago, causing a W=1 warning:
drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:465:5: error: no previous prototype for 'vchiq_platform_init'
Marking it static solves this problem but introduces a new warning
since gcc determines that 'g_fragments_base' is never initialized
in some kernel configurations:
In file included from include/linux/string.h:254,
from include/linux/bitmap.h:11,
from include/linux/cpumask.h:12,
from include/linux/mm_types_task.h:14,
from include/linux/mm_types.h:5,
from include/linux/buildid.h:5,
from include/linux/module.h:14,
from drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:8:
In function 'memcpy_to_page',
inlined from 'free_pagelist' at drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:433:4:
include/linux/fortify-string.h:57:33: error: argument 2 null where non-null expected [-Werror=nonnull]
include/linux/highmem.h:427:9: note: in expansion of macro 'memcpy'
427 | memcpy(to + offset, from, len);
| ^~~~~~
Add a NULL pointer check for this in addition to the static annotation
to avoid both.
