Subject: PCI : remove too specialized __pci_enable_device for default resume
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=924b08f3ff12eb0e8ecd9e9a9b6a5b884a495c23;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

PCI : remove too specialized __pci_enable_device for default resume

Original patch was posted as "PCI : Move pci_fixup_device and is_enabled".
This 1 of 3 patches does:

  - reverts small part of Inaky's patch
    (remove __pci_enable_device)
    This change will be recovered by 3rd patch.

  - temporarily remove pci_fixup_device.
    This change will be recovered by 2nd patch.
