From: Gavin Shan Date: Mon, 27 Feb 2012 20:04:09 +0000 (+0000) Subject: powerpc/eeh: Replace pci_dn with eeh_dev for EEH on pSeries X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=54793d0ef113145c8c0342d9bf2ade5c6b71cba5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git powerpc/eeh: Replace pci_dn with eeh_dev for EEH on pSeries The pci_dn has been replaced with eeh_dev. In order to comply with the rule, the EEH platform implementation on pSeries should also be adjusted for a little bit so that it will depend on eeh_dev instead of pci_dn. The patch replaces pci_dn with eeh_dev. The corresponding information will be retrieved from eeh_dev instead of pci_dn.
