The REQUEST_PROC_DAA command behaves differently from other commands. Sometimes the hardware can auto emit STOP, but in other conditions, it cannot. Improves the code logic to better handle these situations. Hardware can auto emit STOP only when the following conditions are met: - The previous I3C device correctly returns a PID and ACKs an I3C address. - A NACK is received when emitting 7E to try to get the next I3C device's PID. In all other cases, a manual STOP emission is needed. The code is changed to emit STOP when break the while loop and 'return 0' only when the hardware can auto emit STOP.

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 reStructuredText 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.
