Subject: ieee802154: add an mlme_ops call to retrieve PHY object
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=42723448b8bacf60c96812196d7725d8d605d0c4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
