Many uses of strncpy() on xtensa causes a warning like
arch/xtensa/include/asm/string.h:56:42: warning: array subscript is above array bounds [-Warray-bounds]
: "0" (__dest), "1" (__src), "r" (__src+__n)
This avoids the warning by turning the pointer arithmetic into an
integer operation that does not get checked the same way.
