X-Git-Tag: v2.6.21-rc1~273^2~3^2~10^2~15
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2d99c41f05fc2a26737aacf943db03ca89841199;p=pandora-kernel.git

[POWERPC] Mark winbond IDE PCI resources with start 0 as unassigned

libata calls pci_request_regions to claim PCI BAR 0 - 5
pci_request_regions fails if one of the regions cant be claimed.
bar 5 has start == 0,  __request_resource will fail.

Tested on a p630 in SMP mode with pata_sl82c105
