QCA6390 memdump VSE sometimes come to bluetooth driver with wrong sequence number as illustrated as follows: frame # in dec: frame data in hex 1396: ff fd 01 08 74 05 00 37 8f 14 1397: ff fd 01 08 75 05 00 ff bf 38 1414: ff fd 01 08 86 05 00 fb 5e 4b 1399: ff fd 01 08 77 05 00 f3 44 0a 1400: ff fd 01 08 78 05 00 ca f7 41 it is mistook for controller missing packets, so results in page fault after overwriting memdump buffer allocated. Fixed by ignoring QCA6390 sequence number check and checking buffer space before writing.

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.
