2015-02-04coresight-etm: remove check for unknown Kconfig macroPaul Bolle
The CoreSight ETM/PTM driver contains a check for a CONFIG_CORESIGHT_SOURCE_ETM_DEFAULT_ENABLE macro. But there's no related Kconfig symbol CORESIGHT_SOURCE_ETM_DEFAULT_ENABLE. Remove that check and the single line of code it hides.
