Merge branch 'net-sunhme-cleanups-and-logging-improvements' 

Sean Anderson says:

====================
net: sunhme: Cleanups and logging improvements

This series is a continuation of [1] with a focus on logging improvements (in
the style of commit b11e5f6a ("net: sunhme: output link status with a single
print.")). I have included several of Rolf's patches in the series where
appropriate (with slight modifications). After this series is applied, many more
messages from this driver will come with driver/device information.
Additionally, most messages (especially debug messages) have been condensed onto
one line (as KERN_CONT messages get split).
