[ Upstream commit0e45a09a1d] serio_pause_rx() and serio_continue_rx() are usually used together to temporarily stop receiving interrupts/data for a given serio port. Define "serio_pause_rx" guard for this so that the port is always resumed once critical section is over. Example: scoped_guard(serio_pause_rx, elo->serio) { elo->expected_packet = toupper(packet[0]); init_completion(&elo->cmd_done); } Link: https://lore.kernel.org/r/20240905041732.2034348-2-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Stable-dep-of:08bd5b7c9a("Input: synaptics - fix crash when enabling pass-through port") Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
