After commit 42acb06b01b1 ("drm: pahole struct drm_display_mode"), clang warns:
drivers/gpu/drm/omapdrm/omap_connector.c:92:39: warning: braces around scalar initializer [-Wbraced-scalar-init] struct drm_display_mode new_mode = { { 0 } }; ^~~~~~ 1 warning generated.
After the struct was shuffled, the second set of braces is no longer needed because we are not initializing a structure (struct list_head) but a regular integer (int clock).
However, looking into it further, this initialization is pointless because new_mode is used as the destination of drm_mode_copy, where the members of new_mode will just be completely overwritten with the members of mode. Just remove the initialization of new_mode so that there is no more warning and we don't need to worry about updating the initialization if the structure ever get shuffled again.
