From: Mike Leach <mike.leach@xxxxxxxxxx> commit 9204ff94868496f2d9b8b173af52ec455160c364 upstream. CONFIG_CORESIGHT_SOURCE_ETM4X is undefined when built as module, CONFIG_CORESIGHT_SOURCE_ETM4X_MODULE is defined instead. Therefore code in format_attr_contextid_show() not correctly complied when coresight built as module. Use IS_ENABLED(CONFIG_CORESIGHT_SOURCE_ETM4X) to correct this.
