Macro symbol_put() is defined as __symbol_put(__stringify(x))
ksym_name = "jiffies"
symbol_put(ksym_name)
will be resolved as
__symbol_put("ksym_name")
which is clearly wrong. So symbol_put must be replaced with __symbol_put.
When we uninstall hw_breakpoint.ko (rmmod), a kernel bug occurs with the
following error:

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.
