Before this commit, the drm_self_refresh_helper_init() was called in &component_ops.bind() of VOP/VOP2 drivers. The VOP or VPs, which do not want to enable PSR functionality, will also initialize the self refresh helper. Since it wastes resources(e.g., allocating &drm_self_refresh_data and initializing &drm_self_refresh_data.entry_work), we move the init and cleanup process from bind()/unbind() of VOP/VOP2 drivers to the ones of eDP/RGB drivers, which can support PSR functionality.

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.
