Subject: [PATCH V2 0/4] PCI: code clean up on pci configuration space
Date: Tue, 30 Jun 2015 09:16:40 +0800 [thread overview]
Message-ID: <1435627004-6029-1-git-send-email-weiyang@linux.vnet.ibm.com> (raw)
This series is a clean up in the pci subsystem when accessing the pci
configuration space.
The first one is to re-use the PCI_FIND_CAP_TTL to limit the times iterating
in pci configuration space.
The next three are to use the exact type to access the pci cap and pcie ext
cap.
Tested on x86 and powerpc on top of v4.1.
The original thread could be referenced in below link:

---
v1->v2:
* define PCI_FIND_CAP_TTL in drivers/pci/pci.h instead of
include/linux/pci.h
* split the change for return position check from second one, and make the
forth patch
Wei Yang (4):
PCI: move PCI_FIND_CAP_TTL to pci.h and use it in quirks
PCI: use u8 to represent pci configuration space pos and cap
PCI: use u16 to represent pci express extended capabilities pos and
cap
PCI: consolidate return value check for pci_find_(ext_)capability
