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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
