We don't want to overwrite "ret", it already holds the correct error code. The "regmap" variable might be a valid pointer as this point. Fixes: 8f83f26891e1 ("drm/mediatek: Add HDMI support") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
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.
