cros_ec_get_host_command_version_mask() expects to receive sizeof(struct ec_response_get_cmd_versions) from send_command(). The payload is valid only if the return value is positive. Add Kunit tests for returning 0 from send_command() in cros_ec_get_host_command_version_mask(). Note that because the 2 cros_ec_get_host_command_version_mask() use the same `ver_mask`. cros_ec_proto_test_query_all_no_host_sleep_return0() polluates the `ver_mask` and returns 0 on the second send_command() to make sure the second cros_ec_get_host_command_version_mask() doesn't take the garbage from the previous call.

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.
