This change does modify devsw dv_print() to return the int value, enabling walkers to interrupt the walk on non zero value from dv_print(). This will allow the pager_print actually to stop displaying data on user input, and additionally pager is used in various *dev_print callbacks, where it was missing. For test, lsdev [-v] command should display data by screenfuls and should stop when the key 'q' is pressed on pager prompt.
