Subject: [PATCH/RFC 0/2] ALSA: firewire: Fix integer overflows on 32-bit

	Hi all,

This patch series fixes two integer overflows on 32-bit platforms when
in multiplications with the NSEC_PER_SEC constant, found by code
inspection.  They are marked "RFC", as I don't know the maximum transfer
length of MIDI.  Depending on this maximum length, a small tweak may be
necessary.

Thanks for your comments!

  ALSA: fireface: Fix integer overflow in transmit_midi_msg()
  ALSA: firewire-tascam: Fix integer overflow in midi_port_work()

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
