Geert Uytterhoeven e7c22eeaff ALSA: fireface: Fix integer overflow in transmit_midi_msg() ... As snd_ff.rx_bytes[] is unsigned int, and NSEC_PER_SEC is 1000000000L, the second multiplication in ff->rx_bytes[port] * 8 * NSEC_PER_SEC / 31250 always overflows on 32-bit platforms, truncating the result. Fix this by precalculating "NSEC_PER_SEC / 31250", which is an integer constant. Note that this assumes ff->rx_bytes[port] <= 16777.
