clang-14 complains about an unusual way of converting a pointer to an integer:
drivers/misc/cb710/sgbuf2.c:50:15: error: performing pointer subtraction with a null pointer has undefined behavior [-Werror,-Wnull-pointer-subtraction] return ((ptr - NULL) & 3) != 0;
Replace this with a normal cast to uintptr_t.
