Greg,
Please find the changes for coresight and hwtracing subsystem, targeting v6.5.
Please note that, I have pulled James' devm_krealloc_array() patch -
( commit d388f06aced3 "devres: Provide krealloc_array" )
- into the coresight tree from your driver-core-next, for CTI module refcount
fixes depend on it.
Please let me know if this looks alright and kindly pull if it is fine.
Kind regards
Suzuki

coresight: Updates for v6.5
CoreSight and hwtracing subsystem updates for v6.5 includes:
- Fixes to the CTI module reference leaks. This involves,
redesign of how the helper devices are tracked and CTI
devices have been converted to helper devices.
- Fix removal of the trctraceidr file from sysfs for ETMs.
- Match all ETMv4 instances based on the ETMv4 architected
registers and the CoreSight Component ID (CID), than having
to add individual PIDs for CPUs.
- Add support for Dummy CoreSight source and sink drivers.
- Add James Clark as Reviewer for the CoreSight kernel drivers
- Fixes to HiSilicon PCIe Tune and Trace Device driver
