Subject: [PATCH 0/2] coresight: Set affinity to invalid for missing CPU phandle
Date: Thu, 20 Jun 2019 19:15:45 +0530 [thread overview]
Message-ID: <cover.1561037262.git.saiprakash.ranjan@codeaurora.org> (raw)
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.
