Early commit 30ca5cb63c56965 ("staging: sm750fb: change definition of PANEL_PLANE_TL fields") and 27b047bbe1ee9c0 ("staging: sm750fb: change definition of PANEL_PLANE_BR fields") modify the register bit fields definitions. But the modifications are wrong, because the bit mask of "bit field 10:0" is not 0xeff, but 0x7ff. The wrong definition bugs makes display very strange.
