Re: [Pcihpd-discuss] [patch 1/2] acpiphp: allocate resources foradapters with bridges

Allocate resources for adapters with bridges on them.

Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@xxxxxxxxx>
I changed the patch to not store the acpi_handle in the acpiphp_slot
structure, but grab it out of the device structure instead. However, I
don't have an adapter that will really test to see if this works
properly, so if your adapter will work, then please give it a try and
let me know if it fails.
