The necessity of asserting the reset on removal was previously questioned, as DSA's own cleanup methods should suffice to prevent traffic leakage[1]. When a driver has subdrivers controlled by devres, they will be unregistered after the main driver's .remove is executed. If it asserts a reset, the subdrivers will be unable to communicate with the hardware during their cleanup. For LEDs, this means that they will fail to turn off, resulting in a timeout error.

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.
