[ Upstream commit 46f3ceaffa ]
Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable()
to innolux_panel_unprepare(), so they are consistent with
innolux_panel_enable() and innolux_panel_prepare().
This also fixes some mode check and irq timeout issue in MTK dsi code.
Since some dsi code (e.g. mtk_dsi) have following call trace:
1. drm_panel_disable(), which calls innolux_panel_disable()
2. switch to cmd mode
3. drm_panel_unprepare(), which calls innolux_panel_unprepare()
However, mtk_dsi needs to be in cmd mode to be able to send commands
(e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()),
so we need these functions to be called after the switch to cmd mode happens,
i.e. in innolux_panel_unprepare.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
