commitb504a884f6upstream. When the session state is J1939_SESSION_DONE, j1939_tp_rxtimer() will give an alert "rx timeout, send abort", but do nothing actually. Move the alert into session active judgment condition, it is more reasonable. One of the scenarios is that j1939_tp_rxtimer() execute followed by j1939_xtp_rx_abort_one(). After j1939_xtp_rx_abort_one(), the session state is J1939_SESSION_DONE, then j1939_tp_rxtimer() give an alert.

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.
