[PATCH] Fix swsusp with PNP BIOS
swsusp is unable to suspend my machine (DTK FortisPro TOP-5A notebook) with kernel 2.6.17.5 because it's unable to suspend PNP device 00:16 (mouse). The problem is in PNP BIOS. pnp_bus_suspend() calls pnp_stop_dev() for the device if the device can be disabled according to pnp_can_disable(). The problem is that pnpbios_disable_resources() returns -EPERM if the device is not dynamic (!pnpbios_is_dynamic()) but insert_device() happily sets PNP_DISABLE capability/flag even if the device is not dynamic. So we try to disable non-dynamic devices which will fail. This patch prevents insert_device() from setting PNP_DISABLE if the device is not dynamic and fixes suspend on my system.
