I just feared that there might be an interrupt pending on the saa7146 and
inside configure_saa7146 (called from saa7146_init_one()) request_irq is
called before the saa is reset and ints disabled. So I fear that between the
call "request_irq" and "saa7146_write( saa->mem, MC1, 0xbfff0000)" an
interrupt might happen.

Best Regards,
Matthias
