commit 1892bf90677abcad7f06e897e308f5c3e3618dd4 upstream. The kernel test robot found a problem with the ene_ub6250 subdriver in usb-storage: It uses structures containing bitfields to represent hardware bits in its SD_STATUS, MS_STATUS, and SM_STATUS bytes. This is not safe; it presumes a particular bit ordering and it assumes the compiler will not insert padding, neither of which is guaranteed. This patch fixes the problem by changing the structures to simple u8 values, with the bitfields replaced by bitmask constants.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
