[ Upstream commit747ff7d3d7] When rebooting on sc7180 Trogdor devices I see the following crash from the wifi driver. ath10k_snoc 18800000.wifi: firmware crashed! (guid 83493570-29a2-4e98-a83e-70048c47669c) This is because a modem stop event looks just like a firmware crash to the driver, the qmi connection is closed in both cases. Use the qcom ssr notifier block to stop treating the qmi connection close event as a firmware crash signal when the modem hasn't actually crashed. See ath10k_qmi_event_server_exit() for more details. This silences the crash message seen during every reboot.

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.
