Around 3 hunks. For example, in mlx4 the original is

		if (bitmap_intersects(
			ptys2ethtool_link_mode(&ptys2ethtool_map[i],
					       report),
		    link_modes,
		    __ETHTOOL_LINK_MODE_MASK_NBITS))

which was originally converted as

		if (linkmode_intersects(ptys2ethtool_link_mode(&ptys2ethtool_map[i],
							       report),
					link_modes))

and which I rewrote as

		ulong *map_mode = ptys2ethtool_link_mode(&ptys2ethtool_map[i],
							 report);
		if (linkmode_intersects(map_mode, link_modes))

(although upon further review it seems like there should be an
additional blank line there)

Everything I changed should be caught by checkpatch.
