gcc is not smart enough to figure out length was validated before use as strncpy limit, resulting in this warning: inlined from ‘virt_set_oem_table_id’ at ../../hw/arm/virt.c:2197:5: /usr/include/aarch64-linux-gnu/bits/string_fortified.h:106:10: error: ‘__builtin_strncpy’ specified bound depends on the length of the source argument [-Werror=stringop-overflow=] Simplify things by using a constant limit instead.
