The patch below updates SPIN_LOCK_UNLOCKED to __SPIN_LOCK_UNLOCKED since it is
deprected according to my search results.
Note: Keep in mind I am not sure if this is the correct change for this(still learning)
even though it's commented out and such.(figured to give this a try and see).
Signed-off-by: Justin P. Mattock<justinmattock@xxxxxxxxx>
As these were "RFC" I'm not going to apply them.
Care to test them out and see if they really work?
thanks,

well, I went and changed up the patch to test these out. Im not sure how
this app works for this driver(will look into), but just looking at
dmesg gives me an idea of why they commented this out..:
(without patch applied the below shows up as well)

I will try and test this out with the app. other than that seems to be
functioning like the original.
