Commit4a81656c8e("arm64: dts: mediatek: mt8188: Address binding warnings for MDP3 nodes") caused a regression on the MDP functionality when it removed the MT8195 compatibles from the MDP3 nodes, since the MT8188 compatible was not yet listed as a possible MDP component compatible in mdp_comp_dt_ids. This resulted in an empty output bitstream when using the MDP from userspace, as well as the following errors: mtk-mdp3 14001000.dma-controller: Uninit component inner id 4 mtk-mdp3 14001000.dma-controller: mdp_path_ctx_init error 0 mtk-mdp3 14001000.dma-controller: CMDQ sendtask failed: -22 Add the missing compatible to the array to restore 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 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.
