commit2c72eb6286upstream. llc_sap_add_socket() takes a SAP reference for each socket added to a SAP, and llc_sap_remove_socket() releases it. llc_create_incoming_sock() takes an additional SAP reference after adding the child socket. This extra reference was balanced by an explicit llc_sap_put() in llc_ui_release() until commit3100aa9d74("llc: fix SAP reference counting w.r.t. socket handling") removed that put. The corresponding hold in the accept path was left behind. When such a child socket is removed, only the reference taken by llc_sap_add_socket() is released. The extra reference keeps the SAP alive after its last socket is removed. Remove the obsolete hold.

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.
