Subject: [PATCH 1/3] serial: 8250: Allow probe drivers to ignore tx_loadsz
Date: Mon, 25 Mar 2013 13:34:44 +0200 [thread overview]
Message-ID: <1364211286-31611-2-git-send-email-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <1364211286-31611-1-git-send-email-heikki.krogerus@linux.intel.com>
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.
