Su Hui 39b13dce1a firmware: arm_scmi: Fix the double free in scmi_debugfs_common_setup()
Clang static checker(scan-build) throws below warning:
  |  drivers/firmware/arm_scmi/driver.c:line 2915, column 2
  |        Attempt to free released memory.

When devm_add_action_or_reset() fails, scmi_debugfs_common_cleanup()
will run twice which causes double free of 'dbg->name'.

Remove the redundant scmi_debugfs_common_cleanup() to fix this problem.

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 reStructuredText 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.
