But yes, I might have sent the wrong version as I had that same build error and fixed it localy. > it fixes the regression for me, Also now the whole series works for > me :) good to know. What do you want to do now ? Wait for PRCM to become a driver ? Wait for Nishanth's series to get accepted ? I guess the same thing could be done for OMAP3 and AM33, then we would have a chance of having working wake from idle with the new irqchip. cheers -- balbi -------------- next part -------------- A non-text attachment was scrubbed...
