I can't seem to fit even the first one in 2 lines in under 90 columns :/
That is unless I don't indent the second line:

	MT6328_BUCK("buck_vpa", VPA, 500000, 3650000, 50000, buck_volt_range1,
	MT6328_VPA_CON9, MT6328_VPA_CON11, 0x3f, MT6328_VPA_CON12, 
MT6328_VPA_CON7),

Which I don't think is what you meant by fixing the indentation. Can 
you show me an example? With 100 columns on the other hand it seems 
like they should fit.
