It seems that the code for supporting only selected framebuffers
(only HEAD_PANEL fb or only HEAD_CRT fb) is broken anyway as at least
the suspend/resume support assumes that both framebuffers are always
present. Also all sm501fb driver users always try try to initialize
both framebuffers. Therefore I would prefer the removal of non-working
individual framebuffers support (the code that your patch modifies
would be removed as well). Could you please look into it?
