Subject: [PATCH] coresight: etm-perf: Fix define build issue when built as module
Date:   Wed, 14 Apr 2021 20:48:08 +0100
Message-Id: <20210414194808.22872-1-mike.leach@linaro.org>
Precedence: bulk

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.

Fixes: 88f11864cf1d ("coresight: etm-perf: Support PID tracing for kernel at EL2")
