Subject: [PATCH 4/8] Blackfin Serial Driver: move common variables out of serial headers and into the serial driver
Date: Sun, 27 Jul 2008 14:04:03 +0800 [thread overview]
Message-ID: <1217138647-18227-5-git-send-email-cooloney@kernel.org> (raw)
In-Reply-To: <1217138647-18227-1-git-send-email-cooloney@kernel.org>
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)
