Subject: [PATCH 4.4 01/25] serial: 8250_dw: Check the data->pclk when get apb_pclk
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kefeng Wang <wangkefeng.wang@...wei.com>
commit e16b46f190a22587898b331f9d58583b0b166c9a upstream.
It should check the data->pclk, not data->clk when get apb_pclk.
