drm/panel: himax-hx8394: Handle errors from mipi_dsi_dcs_set_display_on() better
...
If mipi_dsi_dcs_set_display_on() returned an error then we'd store
that in the "ret" variable and jump to error handling. We'd then
attempt an orderly poweroff. Unfortunately we then blew away the value
stored in "ret". That means that if the orderly poweroff actually
worked then we're return 0 (no error) from hx8394_enable() even though
the panel wasn't enabled.
Fix this by not blowing away "ret".
Found by code inspection.

The driver shutdown is duplicate as it calls drm_unprepare and
drm_disable which are called anyway when associated drivers are

drm: Explicitly include correct DT includes
...
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
