Subject: [PATCH 08/27] Blackfin Serial Driver: move common variables out of serial headers and into the serial driver
Date: Fri, 10 Oct 2008 11:48:48 +0100	[thread overview]
Message-ID: <20081010104845.31597.37401.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081010103447.31597.42992.stgit@localhost.localdomain>

From: Mike Frysinger <vapier.adi@gmail.com>

move common variables out of serial headers and into the serial driver and
rename "nr_ports" to "nr_active_ports" so as to easily differentiat
between BFIN_UART_NR_PORTS (the # of available) and nr_ports (the # of enabled)
