The KTD253 backlight might already be on when the driver
is probed: then we don't really know what the current
ratio is and all light intensity settings will be off
relative to what it was at boot.
To fix this, bring up the backlight OFF then move it to
the default backlight from there so we know the state.

All amba drivers return 0 in their remove callback. Together with the
driver core ignoring the return value anyhow, it doesn't make sense to
return a value here.
Change the remove prototype to return void, which makes it explicit that
returning an error value doesn't work as expected. This simplifies changing
the core remove callback to return void, too.

The driver core ignores the return value of struct bus_type::remove
because there is only little that can be done. To simplify the quest to
make this function return void, let struct locomo_driver::remove return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea and ensures future
users behave accordingly.

This converts the lms283gf05 backlight driver to use GPIO
descriptors and switches the single PXA Palm Z2 device
over to defining these.
Since the platform data was only used to convey GPIO
information we can delete the platform data header.
Notice that we define the proper active low semantics in
the board file GPIO descriptor table (active low) and
assert the reset line by bringing it to "1" (asserted).

Standard DRM panel driver for DSI command mode panel used by omapfb2 is also
available now. Just like the other panels its module name clashes with the
module from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated
omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver
is disabled, and the DRM panel drivers are useless in that case, make the
omapfb2 panel depend on the standard DRM panels being disabled to fix
the name clash.

BROKEN_GRAPHICS_PROGRAMS is defined when CONFIG_VGA_CONSOLE=y. And
vgacon.c is built exclusively in that case too. So the check for
BROKEN_GRAPHICS_PROGRAMS is pointless in vgacon.c as it is always true.
So remove the test and BROKEN_GRAPHICS_PROGRAMS completely.
This also eliminates the need for vga_font_is_default global as it is
only set and never read.

- Rework omap DSI code, and merge all omapdrm modules now that the last omap panel is now a drm panel.
- More refactoring of omap dsi code.
- Enable 10/12 bpc outputs in vc4.

The controlfb driver has a number of dummy defines for IO operations.
They were introduced in commit a07a63b0e2
("video: fbdev: controlfb: add COMPILE_TEST support").
The write variants did not use their value parameter in the
dummy versions, resulting in set but not used warnings.
Fix this by adding "(void)val" to silence the compiler.

Two W=1 string related warnings.
- Using strncpy to copy string without null-termination generates a
warning. Use memcpy to copy only the relevant chars
- Fix a potential bug with a very long string, subtract one from the
length to make room for the termination null.

Fix several W=1 warnings.
This removes unused code and avoids an assignment by moving
the use inside the conditional block.
The register read FLD_GET(r, 15, 8) could be dropped as it was done a
few lines before too.

The driver core ignores the return value of struct device_driver::remove
because there is only little that can be done. For the shutdown callback
it's ps3_system_bus_shutdown() which ignores the return value.
To simplify the quest to make struct device_driver::remove return void,
let struct ps3_system_bus_driver::remove return void, too. All users
already unconditionally return 0, this commit makes it obvious that
returning an error code is a bad idea and ensures future users behave
accordingly.

Fix set but not used warnings by introducing no_printk variants
for the internal logging system for this driver.
Fix a new warning that popped up now that logging was checked for
correct printf format strings.
A more invasive fix had been to replace all the internal logging with
standard logging primitives - thats for another day.

Fix W=1 warnings:
- Fix kernel-doc

The tmp variable was assigned but the result was never used,
so delete the tmp variable.

Fix warning by deleting the variable. The function call
viafb_get_best_mode() was verified to have no side-effects,
and thus could be dropped too.
