In the vidi_get_modes() function, if either drm_edid_dup() or drm_edid_alloc() fails, the function will immediately return 0, indicating that no display modes can be retrieved. However, in the event of failure in these two functions, it is still necessary to call the subsequent drm_edid_connector_update() function with a NULL drm_edid as an argument. This ensures that operations such as connector settings are performed in its callee function, _drm_edid_connector_property_update. To maintain the integrity of the operation, redundant error handling needs to be removed. Signed-off-by: Wentao Liang <vulab@iscas.ac.cn> Signed-off-by: Inki Dae <inki.dae@samsung.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 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.
