According to the documentation in include/uapi/asm-generic/ioctl.h, _IOW means userspace is writing and kernel is reading, and _IOR means userspace is reading and kernel is writing. In case of these two ioctls, kernel is writing and userspace is reading, so they have to be _IOR instead of _IOW.

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.
