I generally disagree.

Consolidation of these sorts of changes are generally
better done treewide all at once, posted as a series to
a list and maintainers allowing time (weeks to months)
for the specific maintainers to accept them and then
whatever remainder exists reposted and possibly applied
by an overall maintainer (e.g.: Dave M)

Also doubtful.

Subsystem specific local PCI #defines without generic
naming is poor style and makes treewide grep and
refactoring much more difficult.

The atlx maintainers should definitely have been cc'd
on these patches.

Puranjay, can you please do a few things more here:

1: Make sure you use scripts/get_maintainer.pl to cc the
   appropriate people.

2: Show that you compiled the object files and verified
   where possible that there are no object file changes.

3: State that there are no object changes in the proposed
   commit log.

thanks.
