As far as I can tell, this is identical to struct mp5496_smpa2, so
this patch could come down to:

- static const struct regulator_desc mp5496_smpa1 = {
+ static const struct regulator_desc mp5496_smps = {



+	{ "s1", QCOM_SMD_RPM_SMPA, 1, &mp5496_smps, "s1" },
-  	{ "s2", QCOM_SMD_RPM_SMPA, 2, &mp5496_smpa2, "s2" },
+	{ "s2", QCOM_SMD_RPM_SMPA, 2, &mp5496_smps, "s2" },
