Juraj Pecigos 1231363aec nvme-pci: mark Lexar NM760 as IGNORE_DEV_SUBNQN
A system with more than one of these SSDs will only have one usable.
The kernel fails to detect more than one nvme device due to duplicate
cntlids.

[    9.395262] nvme nvme0: pci function 0000:01:00.0

[    1.216145] nvme nvme0: Ignoring bogus Namespace Identifiers
[    1.216261] nvme nvme1: Ignoring bogus Namespace Identifiers

Adding the NVME_QUIRK_IGNORE_DEV_SUBNQN quirk to resolves the issue.

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.
