Mael GUERIN eb2223e2c8 USB: storage: Add unusual-devs entry for Novatek NTK96550-based camera
commit 6ca8af3c8fb584f3424a827f554ff74f898c27cd upstream.

Add the US_FL_BULK_IGNORE_TAG quirk for Novatek NTK96550-based camera
to fix USB resets after sending SCSI vendor commands due to CBW and
CSW tags difference, leading to undesired slowness while communicating
with the device.

Please find below the copy of /sys/kernel/debug/usb/devices with my
device plugged in (listed as TechSys USB mass storage here, the
underlying chipset being the Novatek NTK96550-based camera):

README

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.
