In addition in multiple places the following code sequence is used: 1. Read PCI_STATUS 2. Mask out non-error bits 3. Action based on set error bits 4. Write back set error bits to clear them As this is a repeated pattern, add a helper to the PCI core. Most affected drivers are network drivers. But as it's about core PCI functionality, I suppose the series should go through the PCI tree. v2: - fix formal issue with cover letter v3: - fix dumb typo in patch 7 v4: - add patches 1-3 - move new constant PCI_STATUS_ERROR_BITS to include/linux/pci.h - small improvements in commit messages ==================== Signed-off-by: David S.
