[PATCH v3 09/13] coresight: Convert driver messages to dev_dbg

Suzuki K Poulose
2018-07-26T12:55:16Z

Convert component enable/disable messages from dev_info to dev_dbg.
When used with perf, the components in the paths are enabled/disabled
during each schedule of the run, which can flood the dmesg with these
messages. Moreover, they are only useful for debug purposes. So,
convert such messages to dev_dbg() which can be turned on as
needed.
