Merge branch 'arnd-net-driver-fixes' 

Arnd Bergmann says:

====================
network driver fixes

This is an updated series of fixes for the network device drivers
that showed warnings in ARM randconfig.

Changes since v1 are:

dropped "net: macb: avoid uninitialized variables", already fixed in net-next

dropped "net: fddi/defxx: avoid warning about uninitialized variable
	use", already fixed in net-next

added missing barriers in "net: moxart: use correct accessors for
	DMA memory"

clarified "net: bgmac: clarify CONFIG_BCMA dependency" changelog
====================
