X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=84f4506cb788d85a50c97b399f2999f90e6272b0;p=openwrt%2Fstaging%2Fblogic.git

[PARISC] lba_pci: pci_claim_resources disabled expansion roms

radeonfb was HPMC-ing my C8000 by trying to map its expansion rom from
IO_VIEW, instead of PA_VIEW. Fix seems to be to ensure that its disabled
ROM is properly inserted into the resource tree.

FIXME: this will result in a whinging printk for cards which share expansion
ROMS, such as a quad tulip. Thankfully, it isn't harmful.
