Chen-Yu Tsai d57294c1f8 drm/sun4i: tcon: Unconditionally reset the TCON
When binding the TCON, we were checking the reset control status and
asserting reset if it wasn't in reset. The check failed to account for
the reset control API returning error codes if the status callback was
not implemented.

Since we want the TCON to be reset in all cases, use reset_control_reset
to force a reset instead.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
