Arnd Bergmann 42641042c1 cb710: avoid NULL pointer subtraction 
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.

Fixes: 5f5bac8272 ("mmc: Driver for CB710/720 memory card reader (MMC part)")
