Subject: powerpc/eeh_sysfs: Remove double pci_dn lookup.
X-Git-Tag: v5.6-rc1~63^2~70
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=758b423275f0738fa4d382057c03f3d45c12905d;p=users%2Fjedix%2Flinux-maple.git

powerpc/eeh_sysfs: Remove double pci_dn lookup.

In eeh_notify_resume_show() the pci_dn for the device is looked up once in
the declaration block and then once after checking for a NULL eeh_dev.
Remove the second lookup since it's pointless.
