When a PME wake happens due to a SoundWire wake, we currently clear all WAKESTS bits during the resume operation initiated by the PCI subsystem. As a result, we are unable to identify which SoundWire links need to be resumed and don't properly handle jack detection. This patch only clears the WAKESTS bits for the HDaudio codecs detected earlier. Note that we still clear all WAKESTS bits unconditionally in hda_dsp_ctrl_stop_chip(). The existing behavior is potentially racy if e.g. a jack event happens during a suspend routine, but there's a risk of breaking shutdown or reboot sequences so the code is left as is for now.

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.
