[PATCH v2 0/5] drm/connector: make mode_valid() callback accept const mode pointer
While working on the generic mode_valid() implementation for the HDMI
Connector framework I noticed that unlike other DRM objects
drm_connector accepts non-const pointer to struct drm_display_mode,
while obviously mode_valid() isn't expected to modify the argument.
Mass-change the DRM framework code to pass const argument to that
callback.
The series has been compile-tested with defconfig for x86-64, arm and
arm64.
Note: yes, I understand that this change might be hard to review and
merge. The only viable option that I foresee is to add new callback,
having the const argument and migrate drivers into using it one by one.

Changes in v2:
- Rebased on top of linux-next
- Replaced 'accept const argument' with 'take a const arugment'
(Laurent)
- Link to v1:

[PATCH v2 2/5] drm/amdgpu: don't change mode in amdgpu_dm_connector_mode_valid()
Make amdgpu_dm_connector_mode_valid() duplicate the mode during the

converting the mode_valid() callback of drm_connector to take a const
struct drm_display_mode argument.
