The patch titled
sky2: use pci_config access functions
has been removed from the -mm tree. Its filename was
sky2-use-pci_config-access-functions.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: sky2: use pci_config access functions
From: Stephen Hemminger <shemminger@xxxxxxxxxxxxxxxxxxxx>
Use the PCI layer config access functions. The driver was using the memory
mapped window in device, to workaround issues accessing the advanced error
reporting registers.
