[PATCH] 2.6.3 fix 8250_pnp resource allocation

[PATCH] 2.6.3 fix 8250_pnp resource allocation

[Mark Hindley]

Hi,

Patch below to ensure that 8250_pnp sets necessary flags so that 8250
driver will reserve ioports.

Before, I was logging errors like

Feb 20 08:42:37 titan kernel: Trying to free nonexistent resource <000003e8-000003ef>

on module unload.

Mark
