This patch enhances the firmware reset handler in the Intel Integrated Sensor Hub (ISH) driver. Previously, the ISH firmware would send a MNG_RESET_NOTIFY message in response to an empty IPC message from the ish_wakeup function. With the introduction of the feature to load ISH firmware from the host on the LunarLake platform, the ISH bootloader now involves the IPC function. This results in an additional MNG_RESET_NOTIFY message being sent by ISH bootloader after power on. Consequently, the driver receives two MNG_RESET_NOTIFY messages during system boot up. This can disrupt the dev->dev_state during the first reset flow due to the subsequent reset notify message. To address this, the patch modifies the fw_reset_work_fn function to skip the execution of ishtp_reset_compl_handler during the first reset flow if a reset is pending. The ishtp_reset_compl_handler will then be executed during the second reset flow, ensuring the dev->dev_state is not disrupted.

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.
