[PATCH 3/3] net: mvneta: adjust multiline comments to net/ style
Thomas Petazzoni

Mon Nov 19 06:00:34 EST 2012
As reported by checkpatch, the multiline comments for net/ and
drivers/net/ have a slightly different format than the one used in the
rest of the kernel, so we adjust our multiline comments accordingly.
