While this shouldn't be needed if all devices that claim that they support NCQ autosense (ata_id_has_ncq_autosense()) and/or the sense data reporting feature (ata_id_has_sense_reporting()), actually supported those features. However, there might be some old ATA devices that either have these bits set, even when they don't support those features, or they simply return malformed data when using those features. These devices should be quirked, but in order to try to minimize the impact for the users of these such devices, it was suggested by Damien Le Moal that it might be a good idea to sanity check the sense data received from the device. If the sense data looks bogus, then the sense data is never added to the scsi_cmnd command. Introduce a new function, ata_scsi_sense_is_valid(), and use it in all places where sense data is received from the device.

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.
