[ Upstream commit 4e7487245abcbc5a1a1aea54e4d3b33c53804bda ]
Building with GCC 15 results in build error fs/vboxsf/super.c:24:54: error: initializer-string for array of ‘unsigned char’ is too long [-Werror=unterminated-string-initialization] 24 | static const unsigned char VBSF_MOUNT_SIGNATURE[4] = "\000\377\376\375"; | ^~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors
Due to GCC having enabled -Werror=unterminated-string-initialization[0] by default. Separately initializing each array element of VBSF_MOUNT_SIGNATURE to ensure NUL termination, thus satisfying GCC 15 and fixing the build error.
