Move initialization & deinitialization of 'deinit_lock' mutex lock
inside driver init and deinit respectively alongside other locks
initialization. After following changes no need to maintain client count
variable(client_count) just to init/destroy the lock.

Hi Kalle,

I observed the series status is updated to 'Deferred' state in the 
patchwork link. Since there are no comments in patchwork, so I just 
wanted to confirm if anything is needed from me.


Regards,

Ajay

I don't remember anymore why I deferred it, most likely just to cleanup
my queue, but it's now back in New state. Thanks for the reminder.
