[PATCH net 0/7] Fix MODULE_DESCRIPTION() for net (p6)

[PATCH net 0/7] Fix MODULE_DESCRIPTION() for net (p6)

[Breno Leitao]

There are a few network modules left that misses MODULE_DESCRIPTION(),
causing a warnning when compiling with W=1. Example:

        WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/....

This last patchset solves the problem for all the missing driver. It is
not expect to see any warning for the driver/net and net/ directory once
all these patches have landed.

Breno Leitao (7):
  net: fill in MODULE_DESCRIPTION()s for xen-netback
  net: fill in MODULE_DESCRIPTION()s for ieee802154/fakelb
  net: fill in MODULE_DESCRIPTION()s for plip
  net: fill in MODULE_DESCRIPTION()s for fddik/skfp
  net: fill in MODULE_DESCRIPTION()s for ppp
  net: fill in MODULE_DESCRIPTION()s for mdio_devres
  net: fill in MODULE_DESCRIPTION()s for missing arcnet
