In MIPI I3C Specification: "Ninth Bit of SDR Target Returned (Read) Data as End-of-Data: In I2C, the ninth Data bit from Target to Controller is an ACK by the Controller. By contrast, in I3C this bit allows the Target to end a Read, and allows the Controller to Abort a Read. In SDR terms, the ninth bit of Read data is referred to as the T-Bit (for ‘Transition’)" I3C allow devices early terminate data transfer. So need "actual_len" field to indicate how much get by i3c_priv_xfer.

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.
