From: Brent Pappas <bpappas@xxxxxxxxxxxxxxx> Replace the function-like macros FPNTBL_BYTES(), SCTBL_BYTES(), and MORPH_PLANE_BYTES() with functions to comply with Linux coding style standards. Replace multiplication with calls to array_size() and array3_size() to prevent accidental arithmetic overflow.
