Subject: [PATCH 07/10] mtd nand omap: make debugging output more useful
Date: Tue,  8 Nov 2011 14:01:50 +0100	[thread overview]
Message-ID: <1320757313-12568-8-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1320757313-12568-1-git-send-email-s.hauer@pengutronix.de>

- add missing '\n' at line ends
- fix wrong argument type warnings
- remove too noisy debug in omap_hwcontrol
- add function names to debug printfs
- add 0x prefixes to hex values
