There are few other places where the same change is applicable.
I am planning to put all those changes in a single patch. It includes
changes in drivers/net/ethernet/xscale/ixp4xx_eth.c

You can review this patch separately.

If you are spanning multiple drivers maintained by different
groups, it's probably better to create a patch series, one for
each driver, to allow the various maintainers to apply the
patches to their individually maintained drivers.
