RO and RW of EC may have different EC protocol version. If EC transitions between RO and RW, but AP does not reboot (this is true for fingerprint microcontroller / cros_fp, but not true for main ec / cros_ec), the AP still uses the protocol version queried before transition, which can cause problems. In the case of fingerprint microcontroller, this causes AP to send the wrong version of EC_CMD_GET_NEXT_EVENT to RO in the interrupt handler, which in turn prevents RO to clear the interrupt line to AP, in an infinite loop. Once an EC_HOST_EVENT_INTERFACE_READY is received, we know that there might have been a transition between RO and RW, so re-query the protocol.

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.
