mainlining shenanigans

cros_ec_get_next_event() is documented to return 0 for success and negative for errors. It currently returns negative for some errors, and non-negative (number of bytes received) for success (including some "no data available" responses as zero). This mostly works out OK, because the callers were more or less ignoring the documentation, and only treating positive values as success (and indepdently checking the modification of 'wakeup'). Let's button this up by avoiding pretending to handle event/wakeup distinctions when no event info was retrieved (i.e., returned 0 bytes). And fix the documentation of cros_ec_get_host_event() and cros_ec_get_next_event() to accurately describe their behavior.

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.
