Subject: [PATCH 1/2] serial: 8250: Allow probe drivers to ignore tx_loadsz
Date: Thu, 21 Mar 2013 12:47:47 +0200 [thread overview]
Message-ID: <1363862867-17222-1-git-send-email-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20130321104651.GC2862@xps8300>
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.
