Message-ID: <1340934316.14052.2.camel@phoenix>

Subject: [PATCH RFT] regulator: tps65217: Convert LDO1 to use
regulator_list_voltage_table
Convert tps65217_pmic_ldo1_ops to use regulator_list_voltage_table.
We have n_voltages and volt_table settings in regulator_desc,
so we don't need the table and table_len fields in struct tps_info.
Thus remove them from struct tps_info.
