From 42723448b8bacf60c96812196d7725d8d605d0c4 Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Wed, 4 Nov 2009 17:53:23 +0300 Subject: ieee802154: add an mlme_ops call to retrieve PHY object ops->get_phy should increment reference to wpan-phy. As we return the external structure, we should do refcounting correctly.
