From 6a3f45dccfa3db4de43aabc2f75a337e878f9b4b Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Mon, 25 Mar 2013 13:34:44 +0200 Subject: [PATCH] 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.
