I wanted to keep all local function on top which is used on this file and not the regulator ops. Then implement regulator ops and then probe. Let me see if I can do anything here. > >> + pmic->enable_power_mode[id]) { >> + ret = max77620_regulator_set_power_mode( >> + pmic, pmic->enable_power_mode[id], id); > The 'pmic' argument should be after opening parenthesis, not at new line. This is done for indenting alignment. I am using checkpatch --strict option and for this the next line should be on same column of first charcter after opening parenthesis. To avoid this error, if we want to re-align the indenting for next line then left the line empty after "(". + +static int __init max77620_regulator_init(void) +{ + return platform_driver_register(&max77620_regulator_driver); +} +subsys_initcall(max77620_regulator_init); + > Does it have to be subsys_initcall?

This is basic need of some of driver and hence subsys_initcall. I will move to module_init() as some of other PMIC driver (as3722) is in the module init and used in tegra platform so not seeing much issue on this.
