At some point the orig_video_isVGA field of screen_info was repurposed
for video type. Using it directly for video type check is unsafe as it can
still mean yes (1) or no-output (0) in certain configurations. I had one of those.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on
static/build-time data. Dtschema and Devicetree bindings offer the
static/build-time check for this already.

dss_of_port_get_parent_device() leaks an OF node reference when i >= 2
and struct device_node *np is present. Since of_get_next_parent()
obtains a reference of the returned OF node, call of_node_put() before
returning NULL.
This was found by an experimental verifier that I am developing, and no
runtime test was able to be performed due to that lack of actual
devices.

Do not select BACKLIGHT_CLASS_DEVICE from FB_BACKLIGHT. The latter
only controls backlight support within fbdev core code and data
structures.
Make fbdev drivers depend on BACKLIGHT_CLASS_DEVICE and let users
select it explicitly. Fixes warnings about recursive dependencies,
such as
error: recursive dependency detected!
symbol BACKLIGHT_CLASS_DEVICE is selected by FB_BACKLIGHT
symbol FB_BACKLIGHT is selected by FB_SH_MOBILE_LCDC

symbol DRM_GEM_DMA_HELPER is selected by DRM_PANEL_ILITEK_ILI9341
symbol DRM_PANEL_ILITEK_ILI9341 depends on BACKLIGHT_CLASS_DEVICE
BACKLIGHT_CLASS_DEVICE is user-selectable, so making drivers adapt to
it is the correct approach in any case. For most drivers, backlight
support is also configurable separately.

The sstfb driver currently depends on CONFIG_FB_DEVICE to create sysfs
entries and access info->dev. This patch wraps the relevant code blocks
with #ifdef CONFIG_FB_DEVICE, allowing the driver to be built and used
even if CONFIG_FB_DEVICE is not selected.
The sysfs setting only controls the VGA pass-through state and is not
required for the display to work correctly.

After commit 0edb555a65 ("platform: Make platform_driver::remove()

platform drivers.
Convert all platform drivers below drivers/video/fbdev to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
While touching these files, make indention of the struct initializer
consistent in several files.

The values of the variables xres and yres are placed in strbuf.
These variables are obtained from strbuf1.
The strbuf1 array contains digit characters
and a space if the array contains non-digit characters.
Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres);
more than 16 bytes will be written to strbuf.
It is suggested to increase the size of the strbuf array to 24.

An of_node_put(ep) call was immediately used after a pointer check
for a of_graph_get_remote_port() call in this function implementation.
Thus call such a function only once instead directly before the check.
This issue was transformed by using the Coccinelle software.
