[PATCH] atyfb, rivafb: minor fixes
aty128fb: return an error in the unlikely event that we cannot calculate
some key PLL info
rivafb:
* call CalcStateExt() directly, rather than via function pointers, since
CalcStateExt() is the only value ever assigned to ->CalcStateExt().
* propagate error return back from CalcVClock() through callers
