Subject: pnp: remove extra 0x100 bit from option priority
From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
When building resource options, ISAPNP and PNPBIOS set the priority to
something like "0x100 | PNP_RES_PRIORITY_ACCEPTABLE", but we immediately
mask off the 0x100 again in pnp_build_option(), so that bit looks
superfluous.
Thanks to Rene Herman <rene.herman@xxxxxxxxx> for pointing this out.
