Currently the mutex dedicated to the protection of the list of registered protocols is held during all the protocol initialization phase.
Hi Jonathan,

Such a wide locking region is not needed and causes problem when trying to initialize notifications from within a protocol initialization routine. Reduce the scope of the protocol mutex. Signed-off-by: Cristian Marussi <cristian.marussi@arm.com>I haven't checked carefully that the new scope is appropriate but as a change in of itself, the code is correct and clean. With that in mind.
I will double check after more testing.
