Since cancel_delayed_work(&chip->poweroff_work) does not guarantee that tsl2563_poweroff_work() is not running, tsl2563_set_power(chip, 0) can be called from tsl2563_poweroff_work() after tsl2563_get_power(chip) and tsl2563_set_power(chip, 1) are called. Use _sync version in order to make sure that tsl2563_poweroff_work() is no longer running.

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.
