cb710: avoid NULL pointer subtraction
commit 42641042c10c757fe10cc09088cf3f436cec5007 upstream.
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: 5f5bac8272be ("mmc: Driver for CB710/720 memory card reader (MMC part)")
