Subject: [PATCH v3 0/2] mfd: intel-lpss: refactor PCI probe and common IRQ check

The PCI code can be refactored to use respective PCI APIs instead of
direct dereference of struct pci_dev members.

With that, we may unshadow the error code that is promoted in the irq
field of info structure. PCI core shouldn't propagate 0 as a value
there, and in case it happens it reveals a bug somewhere else.

Changelog:

v2 -> v3:
1. Refactored PCI glue driver a bit (a new patch)
2. Updated commit message in the original patch

v1 -> v2:
1. Update commit message
2. Fix IRQ check in intel_lpcc_probe()

Andy Shevchenko (1):
  mfd: intel-lpss: Use PCI APIs instead of derefereincing

Chen Ni (1):
  mfd: intel-lpss: Amend IRQ check
