The fields, "toc" and "cd_info", of "struct gdrom_unit gd" are allocated in "probe_gdrom()". Prevent a memory leak by making sure "gd.cd_info" is deallocated in the "remove_gdrom()" function. Also prevent double free of the field "gd.toc" by moving it from the module's exit function to "remove_gdrom()". This is because, in "probe_gdrom()", the function makes sure to deallocate "gd.toc" in case of any errors, so the exit function invoked later would again free "gd.toc". The patch also maintains consistency by deallocating the above mentioned fields in "remove_gdrom()" along with another memory allocated field "gd.disk".

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.
