Date: Wed, 14 Sep 2016 11:50:36 +0800 From: <sean.wang@...iatek.com> To: <john@...ozen.org>, <davem@...emloft.net> CC: <nbd@...nwrt.org>, <netdev@...r.kernel.org>, <linux-mediatek@...ts.infradead.org>, <keyhaede@...il.com>, <objelf@...il.com>, Sean Wang <sean.wang@...iatek.com> Subject: [PATCH net-next 2/7] net: ethernet: mediatek: add mtk_hw_deinit call as the opposite to mtk_hw_init call From: Sean Wang <sean.wang@...iatek.com> grouping things related to the deinitialization of what mtk_hw_init call does that help to be reused by the reset process and the error path handling.
