Subject: staging: vc04_services: changen strncpy() to strscpy_pad()
From: Arnd Bergmann <arnd@xxxxxxxx>
commit ef25725b7f8aaffd7756974d3246ec44fae0a5cf upstream.
gcc-14 warns about this strncpy() that results in a non-terminated
string for an overflow:
In file included from include/linux/string.h:369,
from drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c:20:
In function 'strncpy',
inlined from 'create_component' at drivers/staging/vc04_services/vchiq-mmal/mmal-vchiq.c:940:2:
include/linux/fortify-string.h:108:33: error: '__builtin_strncpy' specified bound 128 equals destination size [-Werror=stringop-truncation]
Change it to strscpy_pad(), which produces a properly terminated and
zero-padded string.
