The mcp2221_raw_event retrieves the value and direction of gpio on the same command, by setting the value on mcp->status and the direction on mcp->gpio_dir; and the offset at which they are read is based on mcp->gp_idx, set by the gpiochip callbacks. However, the individual gpiochip calls set the index to look for directly on the field they want to track. This create a "double offset" in the final read in the response report. Align the behaviour of mcp2221_raw_event and mcp_gpio_get/mcp_gpio_get_direction by putting gp_idx on those calls to the base offset of the gpio status struct.

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.
