[PATCH 02/10] PCI: dwc: *all*: Add platform_set_drvdata

Kishon Vijay Abraham I
2017-02-15T13:24:50Z

Add platform_set_drvdata in all designware based drivers to store the
private data structure of the driver so that dev_set_drvdata can be
used to get back private data structure in add_pcie_port/host_init.
This is in preparation for splitting struct pcie_port into core and
host only structures. After the split pcie_port will not be part of
the driver's private data structure and *container_of* used now
to get the private data pointer cannot be used.
