coresight: cpu-debug: Replace mutex with mutex_trylock on panic notifier (2022-05-09 16:03:24 +0100)
---------------------------------------------------------------- Coresight changes for v5.19
Good day Greg,
Please consider those for the the upcoming v5.19 merge window when you have time.
This pull request includes:
- Work to uniformise access to the ETMv4 registers, making it easier to look for and change register accesses.
- A correction to a probing failure when looking for links between devices.
- The replacement of a call to mutex_lock() with a mutex_trylock() in the panic notifier of the cpu-debug infrastructure to avoid a possible deadlock.
