pnp_manual_config_dev is intented for drivers that use different
resource assignments than those automatically set by PnP.  It looks
like you're passing the same config back.

Could you please explain your rational here further.

Values already assigned by the BIOS are not checked against reserved
regions.  Is this what you're getting it?  If so, we could have double
detection issues between the PnP protocol and the legacy detection
mechanism.

My idea was just to enforce pnp_reserve_{io,irq} options for serial
ports too (8250_pnp does not check for those options). I was looking for a
way of ignoring a serial port I/O range (before Russell King point me to
setserial).
So, yes, please drop this patch as my problem is already solved in a
different (and much better) way. :)
