Currently we do reset for each RDDM event from MHI, however there are cases, see below log, that we get two or more consecutive events, and it is pointless to do reset for the subsequent ones. What's more, it makes reset process more likely to fail. [ 103.289864] mhi mhi0: System error detected [ 103.289871] ath12k_pci 0000:03:00.0: mhi notify status reason MHI_CB_EE_RDDM [ 103.293144] mhi mhi0: System error detected [ 103.293150] ath12k_pci 0000:03:00.0: mhi notify status reason MHI_CB_EE_RDDM Add a check to avoid reset again and again. This is done by tracking previous MHI status: if we receive a new RDDM event while the previous event is also the same, we treat it as duplicate and ignore it, because normally we should at least receive a MHI_CB_EE_MISSION_MODE event between them.

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.
