The following functions test whether their argument is NULL and then
return immediately.
* backlight_device_unregister
* drm_gem_object_unreference_unlocked
Thus the test around the calls is not needed.
This issue was detected by using the Coccinelle software.

omapdrm is using much too generic Kconfig names for its panels and

The backlight GPIO was supported with platform data only. Now that the
driver only supports DT, the backlight GPIO is never initialized. Remove
it.

To allow supporting displays that need some logic to enable power to the
display try to get a vcc-supply property from the device tree and drive
the resulting regulator accordingly.

Some displays have a reset input. To assert that the display is
functional the reset gpio must be deasserted.
Teach the driver to get and drive such a gpio accordingly.

In legacy mode (non DT mode) support only composite connector type. The
only user for this is rx51, using composite type.
Dropping the connector_type selection via pdata will allow cleanups in
omapdss (drm vs fbdev).

A lot of the display drivers for OMAP use the gpio descriptor functions
that are only available in linux/gpio.h if GPIOLIB is enabled and
otherwise produce a build error:

This replaces the existing linux/gpio.h with linux/gpio/consumer.h
where needed. In case of panel-lgphilips-lb035q02.c however, we
also have to include linux/gpio.h to get the definition of gpio_is_valid
and gpio_set_value_cansleep that are used for the non-DT case.

tpd12s015 HW has LS_OE, CT_CP_HPD and HPD gpios. Out of these gpios,
driver only handled LS_OE as optional. The CT_CP_HPD gpio should also
be treated as optional gpio as it is just a power saving feature. Some
boards hardwire this gpio to be always enable. In this patch, all access
to CT_CP_HPD gpio is made optional.

Now that omapdss is only for omapdrm, we can change omapdrm to select
OMAP2_DSS to enable omapdss if omapdrm is enabled, instead of omapdrm
depending on omapdss.
We can also change omapdss and the display drivers to depend on
DRM_OMAP, so that they are only visible under omapdrm in menuconfig.

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.
We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.
