Mark switch cases where we are expecting to fall through.
This patch fixes the following warning (Building: arm):
drivers/hsi/clients/ssi_protocol.c: In function ‘ssip_set_rxstate’:
drivers/hsi/clients/ssi_protocol.c:291:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (atomic_read(&ssi->tx_usecnt))
^
drivers/hsi/clients/ssi_protocol.c:294:2: note: here
case RECEIVING:
^~~~
drivers/hsi/clients/ssi_protocol.c: In function ‘ssip_keep_alive’:
drivers/hsi/clients/ssi_protocol.c:466:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (atomic_read(&ssi->tx_usecnt) == 0)
^
drivers/hsi/clients/ssi_protocol.c:472:3: note: here
case SEND_IDLE:

Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.

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.
