This is a note to let you know that I've just added the patch titled

coresight: etm-perf: Fix define build issue when built as module

to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-testing branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open.

If you have any questions about this process, please let me know.

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.
