[PATCH 0/2] coresight: Set affinity to invalid for missing CPU phandle

From: Sai Prakash Ranjan

In case of missing CPU phandle, the affinity is set default to
CPU0 which is not a correct assumption and leads to crashes
in few cases. Fix this by returning -ENODEV in coresight
platform and abort the probe in coresight etm and cpu-debug
drivers.
