From: Santosh Nayak <santoshprasadnayak@xxxxxxxxx> If locking attempt was interrupted by a signal then we should return -EINTR so that caller can take appropriate action. We have 3 callers: gigaset_probe(), gigaset_tty_open() and gigaset_probe(). Each caller tries to free allocated memory if lock fails. This is possible if we returns -EINTR.
