Babu Moger fc747eebef x86/resctrl: Remove redundant variable in mbm_config_write_domain() 
The kernel test robot reported the following warning after commit

  54e35eb861 ("x86/resctrl: Read supported bandwidth sources from CPUID").

even though the issue is present even in the original commit

  92bd5a1390 ("x86/resctrl: Add interface to write mbm_total_bytes_config")

which added this function. The reported warning is:

  $ make C=1 CHECK=scripts/coccicheck arch/x86/kernel/cpu/resctrl/rdtgroup.o
  ...
  arch/x86/kernel/cpu/resctrl/rdtgroup.c:1621:5-8: Unneeded variable: "ret". Return "0" on line 1655

Remove the local variable 'ret'.

  [ bp: Massage commit message, make mbm_config_write_domain() void. ]

README 

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.
