GCC fails to build ps3_defconfig with the following errors:
arch/powerpc/platforms/ps3/repository.c: In function ‘make_first_field.constprop’:
arch/powerpc/platforms/ps3/repository.c:78:9: error: ‘strnlen’ specified bound 8 exceeds source size 3 [-Werror=stringop-overread]
78 | memcpy((char *)&n, text, strnlen(text, sizeof(n)));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
arch/powerpc/platforms/ps3/repository.c: In function ‘make_first_field.constprop’:
arch/powerpc/platforms/ps3/repository.c:78:9: error: ‘strnlen’ specified bound 8 exceeds source size 4 [-Werror=stringop-overread]
78 | memcpy((char *)&n, text, strnlen(text, sizeof(n)));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The current use of strnlen(text, sizeof(n)) triggers -Wstringop-overread
when text is a short string literal that is smaller than sizeof(n), such
as "bi" or "bus". Use strlen(text) instead and clamp the copy length to
sizeof(n) before memcpy().
Drop the redundant char * cast while at it.
