Message-Id: <1323450440-414-9-git-send-email-w.sang@pengutronix.de> Date: Fri, 9 Dec 2011 18:07:20 +0100 From: Wolfram Sang <w.sang@...gutronix.de> To: linux-serial@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Greg KH <gregkh@...e.de>, Alan Cox <alan@...ux.intel.com>, Claudio Scordino <claudio@...dence.eu.com>, Wolfram Sang <w.sang@...gutronix.de> Subject: [PATCH RESEND 8/8] serial: 8250: fix comment about accessing EMSR All docs I checked do say LCR should NOT be 0xBF (16c850, 16c854, 16v2750). Fix it according to that, since the only usage of the register currently implements the revised access method. If somebody later finds a derivate which actually does need 0xBF to enable that register, we can update the comment again with precise references.
