The commit5ea6b17027("drm/panel: Add prepare_prev_first flag to drm_panel") and commit0974687a19("drm/bridge: panel: Set pre_enable_prev_first from drmm_panel_bridge_add") added handling of panel's prepare_prev_first to devm_panel_bridge_add() and drmm_panel_bridge_add(). However if the driver calls drm_panel_bridge_add_typed() directly, then the flag won't be handled and thus the drm_bridge.pre_enable_prev_first will not be set. Move prepare_prev_first handling to the drm_panel_bridge_add_typed() so that there is no way to miss the flag.

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.
