Subject[PATCH 4.7 02/45] serial: 8250_dw: Check the data->pclk when get apb_pclk
Date
4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kefeng Wang <wangkefeng.wang@huawei.com>

commit e16b46f190a22587898b331f9d58583b0b166c9a upstream.

It should check the data->pclk, not data->clk when get apb_pclk.

Fixes: c8ed99d4f6a8("serial: 8250_dw: Add support for deferred probing")
