[PATCH 3/4] mtd: nand: replace DEBUG() with dev_dbg()

Brian Norris computersforpeace at gmail.com
Tue Jun 7 19:01:56 EDT 2011


Start moving away from the MTD_DEBUG_LEVEL messages. The dynamic
debugging feature is a generic kernel feature that provides more
flexibility.

(See Documentation/dynamic-debug-howto.txt)
