[RFT][PATCH 1/2] phy: bcm-ns2-pcie: Get rid of struct ns2_pci_phy

From: Axel Lin <hidden>
Date: 2016-06-24 16:25:08

By setting phy_set_drvdata(phy, mdiodev), struct ns2_pci_phy can be
removed.

[RFT][PATCH 2/2] phy: bcm-ns2-pcie: Set missing .owner field in ns2_pci_phy_ops

From: Axel Lin <hidden>
Date: 2016-06-24 16:26:13

Add missing .owner field in ns2_pci_phy_ops, which is used for refcounting.
While at it, also makes ns2_pci_phy_ops const as it's never modified.
