Author: Milan Broz Date: Thu Dec 10 23:51:53 2009 +0000 dm: sysfs add empty release function to avoid debug warning This patch just removes an unnecessary warning: kobject: 'dm': does not have a release() function, it is broken and must be fixed. The kobject is embedded in mapped device struct, so code does not need to release memory explicitly here.
