[PATCH v8 0/7] Add pci_dev_for_each_resource() helper and update users

[Andy Shevchenko]

Provide two new helper macros to iterate over PCI device resources and
convert users.

Looking at it, refactor existing pci_bus_for_each_resource() and convert
users accordingly.

Note, the amount of lines grew due to the documentation update.

Changelog v8:
- fixed issue with pci_bus_for_each_resource() macro (LKP)
- due to above added a new patch to document how it works
- moved the last patch to be #2 (Philippe)
- added tags (Philippe)

Changelog v7:
- made both macros to share same name (Bjorn)
- split out the pci_resource_n() conversion (Bjorn)

Changelog v6:
- dropped unused variable in PPC code (LKP)

Changelog v5:
- renamed loop variable to minimize the clash (Keith)
- addressed smatch warning (Dan)
- addressed 0-day bot findings (LKP)

Changelog v4:
- rebased on top of v6.3-rc1
- added tag (Krzysztof)

Changelog v3:
- rebased on top of v2 by Mika, see above
- added tag to pcmcia patch (Dominik)

Changelog v2:
- refactor to have two macros
- refactor existing pci_bus_for_each_resource() in the same way and
  convert users
