[PATCH v3 0/4] fpga: don't use drvdata in common code

[Alan Tull]

Setting drvdata is fine for DT based devices which have one manager,
bridge, or region device per platform device.  However, PCIe based
devices may have multiple FPGA mgr/bridge/regions under one PCIe
device.  Without these changes, PCIe-based solutions have to create an
extra device for each child mgr/bridge/region to hold drvdata.

Also changing the fpga_*_register/unregister functions to take the
corresponding struct as the only parameter wherever they weren't already.

* int fpga_bridge_register(struct fpga_bridge *br)
* int fpga_mgr_register(struct fpga_manager *mgr)
* int fpga_region_register(struct fpga_region *region)

* void fpga_bridge_unregister(struct fpga_bridge *br)
* void fpga_mgr_unregister(struct fpga_manager *mgr)
* int fpga_region_unregister(struct fpga_region *region)

Changes from v2:
* Drop patch 5 which fixed a DT overlay issue.  The underlying
  issue was fixed in the main DT overlay code.
* Minor code cleanup to make it more obvious that the changes
  were not breaking anything
* Added Moritz' ack on patch 1

  fpga: region: don't use drvdata in common fpga code
  fpga: manager: don't use drvdata in common fpga code
  fpga: bridge: don't use drvdata in common fpga code
  fpga: region: change fpga_region_register to have one param
