Currently the code will set US_FL_SANE_SENSE flag unconditionally if device claims SPC3+, however we should allow US_FL_BAD_SENSE flag to prevent this behavior, because SMI SM3350 UFS-USB bridge controller, which claims SPC4, will show strange behavior with 96-byte sense (put the chip into a wrong state that cannot read/write anything). Check the presence of US_FL_BAD_SENSE when assuming US_FL_SANE_SENSE on SPC4+ devices.

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.
