Uwe Kleine-König 4511b3650e coresight: etm4x: Remove bogous __exit annotation for some functions ...

[ Upstream commit 348ddab81f ]

etm4_platform_driver (which lives in ".data" contains a reference to
etm4_remove_platform_dev(). So the latter must not be marked with __exit
which results in the function being discarded for a build with
CONFIG_CORESIGHT_SOURCE_ETM4X=y which in turn makes the remove pointer
contain invalid data.

etm4x_amba_driver referencing etm4_remove_amba() has the same issue.

Drop the __exit annotations for the two affected functions and a third
one that is called by the other two.

For reasons I don't understand this isn't catched by building with
CONFIG_DEBUG_SECTION_MISMATCH=y.

Fixes: 5214b56358 ("coresight: etm4x: Add support for sysreg only devices")
