drm: Rename dp/ to display/

2022-04-25T09:17:45+00:00

Rename dp/ to display/ to account for additional display-related
helpers, such as HDMI. Update all related include statements. No
functional changes.

Various drivers, such as i915 and amdgpu, use similar naming scheme
by putting code for video-output standards into a local display/
directory. The new directory's name is aligned with this convention.

drm/gma500: fix a potential repeat execution in psb_driver_load

2022-04-20T07:11:01+00:00

Instead of exiting the loop as expected when an entry is found, the
list_for_each_entry() continues until the traversal is complete. To
avoid potential executing 'ret = gma_backlight_init(dev);' repeatly,
goto outside the loop when found entry by replacing switch/case with
if statement.

gma500: fix an incorrect NULL check on list iterator

2022-03-29T09:33:11+00:00

The bug is here:
	return crtc;

The list iterator value 'crtc' will *always* be set and non-NULL by
list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the list is empty or no element is found.

To fix the bug, return 'crtc' when found, otherwise return NULL.

drm/gma500: Free the correct connector allocation

2022-03-23T10:20:45+00:00

The allocation is made for the gma_connector object so we must use the
same address when free()ing the object.

hotpluggable. No connectors in gma500 are hotpluggable.
