Since the rcdev structure is allocated by the reset controller drivers themselves, they need to exists as long as there is a consumer. A call to module_get() is already existing but that does not work when using device-tree overlays. In order to guarantee that the underlying reset controller device does not vanish while using it, add a get_device() call when retrieving a reset control from a reset controller device and a put_device() when releasing that control.

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.
