a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A 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. 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.
