[ Upstream commit 123ee07ba5b7123e0ce0e0f9d64938026c16a2ce ] Smatch reports: drivers/gpu/drm/sun4i/sun4i_tcon.c:805 sun4i_tcon_init_clocks() warn: 'tcon->clk' from clk_prepare_enable() not released on lines: 792,801. In the function sun4i_tcon_init_clocks(), tcon->clk and tcon->sclk0 are not disabled in the error handling, which affects the release of these variable. Although sun4i_tcon_bind(), which calls sun4i_tcon_init_clocks(), use sun4i_tcon_free_clocks to disable the variables mentioned, but the error handling branch of sun4i_tcon_init_clocks() ignores the required disable process. To fix this issue, use the devm_clk_get_enabled to automatically balance enable and disabled calls. As original implementation use sun4i_tcon_free_clocks() to disable clk explicitly, we delete the related calls and error handling that are no longer needed. Fixes: |

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.
