Put the update of the power.smart_suspend device flag under the PM spinlock of the device in case multiple bit fields in struct dev_pm_info occupy one memory location which needs to be updated via RMW every time any of these bit fields is updated. The lock in question is already held around the power.direct_complete flag update in device_prepare() for the same reason, so this change does not add locking-related overhead to the code.

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.
