The SRF/DVFS + CPUFreq patches had issues booting on
non-3430SDP platforms as reported by Kevin Hilman.
This patch puts non-NULL checks in place for mpu_opps/dsp_opps
/l3_opps before accessing them and fixes the issue.
This fix/patch can be applied on top of
pm-20081119 branch
+ [PATCH 00/08] OMAP3 SRF: OPP and Frequency resources
+ [PATCH 00/03] OMAP3 PM: CPUFreq driver for OMAP3

Thanks, I'll pull this fix along with the above two series into
the next PM branch (which should be out later today.)
