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.

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.

6ea970a9be regulator: act8865: Use of_get_child_by_name
of_find_node_by_name walks the allnodes list, and can thus walk
outside of the parent node. Use of_get_child_by_name instead.

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.
