Subject: [PATCH v2 0/4] PCI: Resource helper improvements

This series introduces resource_set_{range,size}() helpers to replace
often repeated code fragments to set resource start and end addresses.
The last two patches clean up nearby code.

For now, this series only converts PCI subsystem. There are plenty of
resource start/end setting code elsewhere in the kernel but those can
be converted once the helpers reach Linus' tree.

v2:
- Improved commit message
- Added patch to introduce ALIGN_DOWN_IF_NONZERO()

Ilpo Järvinen (4):
  resource: Add resource set range and size helpers
  PCI: Use resource_set_{range,size}() helpers
  PCI: Use align and resource helpers, and SZ_* in quirk_s3_64M()
  PCI: Introduce ALIGN_DOWN_IF_NONZERO() helper locally
