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.
