Anders Roxell cdb2d3ee04 arm64: KVM: hyp: debug-sr: Mark expected switch fall-through
When fall-through warnings was enabled by default the following warnings
was starting to show up:

../arch/arm64/kvm/hyp/debug-sr.c: In function ‘__debug_save_state’:
../arch/arm64/kvm/hyp/debug-sr.c:20:19: warning: this statement may fall
 through [-Wimplicit-fallthrough=]
  case 15: ptr[15] = read_debug(reg, 15);   \
../arch/arm64/kvm/hyp/debug-sr.c:113:2: note: in expansion of macro ‘save_debug’
  save_debug(dbg->dbg_bcr, dbgbcr, brps);
  ^~~~~~~~~~

Rework to add a 'Fall through' comment where the compiler warned
about fall-through, hence silencing the warning.

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.
