Subject: [PATCH 7/9] Samsung/serial: move the decision about an improved UART into Kconfig
Date: Fri, 20 Jul 2012 21:29:43 +0200	[thread overview]
Message-ID: <1342812585-22017-8-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1342812585-22017-1-git-send-email-jbe@pengutronix.de>

More or less just cosmetic (removing ifdefs!).
