'DEBUG' needs to be defined for dev_dbg() to have any effect. Not quite. If CONFIG_DYNAMIC_DEBUG is set, these dev_dbg statements are compiled in but not by default set to emit output. Output can be enabled by using dynamic_debug controls like: # echo -n 'file omap4iss/* +p' > <debugfs>/dynamic_debug/control See Documentation/dynamic-debug-howto.txt for more details. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
