[PATCH 3/12] net: assign PDE->data before gluing PDE into /proc tree

From: Denis V. Lunev
Date: Tue Apr 29 2008 - 07:16:36 EST


Simply replace proc_create and further data assigned with proc_create_data.
Additionally, there is no need to assign NULL to PDE->data after creation,
/proc generic has already done this for us.
