Hi all.
I've not received any feedback about this patch, so I'm resending just
to check if someone is going to take care of it.
The patch fixes the usage of device_trylock inside the driver umc-bus.c:
device_trylock has the same semantics of mutex_trylock, so it returns 1
if the lock has been acquired successfully.
Best regards,
Claudio
