2c12992787 regulator: lp872x: Kill _rdev_to_offset() function
There is only one user calling _rdev_to_offset() function.
Remove _rdev_to_offset() makes the code simpler.

5bab305d3c regulator: lp872x: remove unnecessary function
The lp872x_check_dvs_validity() is used for checking DVS platform data.
 If the DVS platform data is not defined, return as error code.
 Now, this is unnecessary because the default DVS mode is set in this case.

9d6da6fcc2 regulator: lp872x: fix NULL pointer access problem
The lp872x_set_dvs() is used for changing the DVS pin state.
 This function works only when the DVS platform data is defined.
 So don't assume that DVS data is always valid.
 In case the platform data is not defined, the DVS data is set to NULL
 for skipping the DVS pin control.

 DVS selection and GPIO pin number are used for the LP872x DVS pin control.
 For better readability, DVS selection argument is added in lp872x_set_dvs().

86b3fef0c7 regulator: lp872x: initialize the DVS mode
The platform specific configuration(general_config) is optional.
 However, the DVS settings should be configured explicitly while
 loading the driver.
 This patch enables configuring the default DVS mode even though
 the platform data is not defined.

b158fba605 regulator: lp872x: set the default DVS mode
The lp872x driver has the DVS platform data which select the register address
 of the BUCK voltage.
 This patch enables updating the default DVS mode when the DVS platform data
 is not defined.

5bae062830 regulator: lp872x: Simplify implementation of lp872x_find_regulator_init_data()
Pass regulator id rahter than the index to lp872x_find_regulator_init_data(),
then the code can be simpler.
We can also get max_regulators by lp->num_regulators.

baf73e2c4e regulator: lp872x: Return -EINVAL if pdata is NULL
