Wentao Guan ab35ad950d nvme-pci: add quirks for WDC Blue SN550 15b7:5009 
Add two quirks for the WDC Blue SN550 (PCI ID 15b7:5009) based on user
reports and hardware analysis:

 - NVME_QUIRK_NO_DEEPEST_PS:
	liaozw talked to me the problem and solved with
	nvme_core.default_ps_max_latency_us=0, so add the quirk.
	I also found some reports in the following link.

 - NVME_QUIRK_BROKEN_MSI:
	after get the lspci from Jack Rio.
	I think that the disk also have NVME_QUIRK_BROKEN_MSI.
	described in commit d5887dc6b6 ("nvme-pci: Add quirk for broken MSIs")
	as sean said in link which match the MSI 1/32 and MSI-X 17.

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 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.
