Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) produced these warnings:

drivers/net/ethernet/marvell/mvneta_bm.c: In function 'mvneta_bm_construct':

  a0627f776a45 ("net: marvell: Allow drivers to be built with COMPILE_TEST")

"a few warnings" is a matter of perception.  :-(

Please fix these up.
