Date: Thu, 21 Mar 2013 12:47:47 +0200 From: Heikki Krogerus <heikki.krogerus@...ux.intel.com> To: Ley Foon Tan <lftan@...era.com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Jiri Slaby <jslaby@...e.cz>, Rob Landley <rob@...dley.net>, linux-kernel@...r.kernel.org, linux-serial@...r.kernel.org Subject: [PATCH 1/2] serial: 8250: Allow probe drivers to ignore tx_loadsz In most cases the tx_loadsz is the same as fifosize. This will store the fifosize in it if it was not separately delivered from the driver.
