Message-Id: <1411367422-2095-1-git-send-email-ssreedharan@mvista.com> Date: Mon, 22 Sep 2014 12:00:22 +0530 From: Sudhir Sreedharan <ssreedharan@...sta.com> To: linux-serial@...r.kernel.org Cc: gregkh@...uxfoundation.org, jslaby@...e.cz, linux-kernel@...r.kernel.org, Sudhir Sreedharan <ssreedharan@...sta.com> Subject: [PATCH] serial/core: Initialize the console pm state For console devices having UART_CAP_SLEEP capability, the uart_pm_state has to be initialized to UART_PM_STATE_ON. Otherwise the LCR regiser values are reinitialized when uart_change_pm is called from uart_configure_port.
