+++ This bug was initially created as a clone of Bug #149467 +++ Description of problem: /usr/sbin/lockdev works only for 2-component pathnames ("/dev/something") and does not check for 3-component pathnames such as /dev/input/ttyACM0. minicom and other applications expect "/usr/sbin/lockdev -l /dev/arbitrary/path/name" to work, but it doesn't, and the error diagnosis is cryptic and/or misleading. Either lockdev should work with an arbitrary pathname below /dev, or lockdev should be verbose and informative about the error, or all applications that use lockdev should be fixed to detect 3 or more components in a pathname (and then adapt appropriately.)
