Beniamino Galvani 34e0247ffc regulator: act8865: fix build when OF is not enabled
act8846_matches and act8865_matches are defined only when OF is
enabled. Move references to them to the act8865_pdata_from_dt()
function to avoid a build error when OF is disabled.

Beniamino Galvani bbb83f38a8 regulator: act8865: set correct number of regulators in pdata
act8865_pdata_from_dt() populates the array pdata->regulators with all
the regulators and then assigns the field init_data only for the ones
actually found in the DT.

The patch changes the value assigned to pdata->num_regulators to match
the size of the array.

Beniamino Galvani 48a1e1b50d regulator: act8865: fix parsing of platform data
The driver loops through all available regulators (ACT8865_REG_NUM)
and accesses pdata->regulators[i].platform_data without checking the
actual value of num_regulators in platform data, potentially causing a
invalid memory access.

Fix this and look up the regulator init_data by id in platform data.

Axel Lin fb8eb45400 regulator: act8865: Remove unnecessary *rdev[] from struct act8865
Now we are using devm_regulator_register(), so we don't need the *rdev[] array
to store return value of devm_regulator_register. Use a *rdev variable is
enough for checking return status.

Wenyou Yang d04b755273 regulator: act8865: register all regulators regardless of how many are used
As Mark pointed out, the driver should register all regulators
regardless of how many are used in the system in order to aid diagnostics.

But in the previous patch, only register the regulators that are used.
