The error checks in mmc_blk_add_debugfs() and mmc_blk_remove_debugfs() are extraneous. Therefore, this patch removes all error checks from both functions. Additionally, mmc_blk_add_debugfs() has been changed to return void instead of an integer value that was never used. This simplifies the function and improves its clarity.

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.
