From: Santosh Nayak <santoshprasadna...@gmail.com>
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.
