* Modules now print their version number and date on insertion * Some printk statements missed a \n * 'make clean' now works, even if some .d (dependency) files contain garbage. Note that *only* 'make clean' helps in that case; 'make clean all', for example, will fail! There is really no nice way to solve that. git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@11 7894878c-1315-0410-8ee3-d5d059ff63e0
