[PATCH v3 0/9] coresight: change some driver' spinlock type to raw_spinlock_t

Hi Mike.

But I wonder etmv3 needs to change. Because its spinlock is used only
via sysfs enable/disable path.
So, I think it doesn't need to change the lock type.

Actually, I couldn't find out the path where
the STM's lock could be grabbed under other raw_spin_lock (including csdev)
If you don't mind would you let me the code path please?

Thanks
