pdata contains an array of struct act8865_regulator_data and a
num_regulators field which should hold the number of elements in the
array, if I understand correctly.

So in the current code, when populating platform data from DT, there
is a mismatch between the number of elements that are put in the array
(ARRAY_SIZE(act8865_matches)) and the value of num_regulators, which
is set to the number of regulators found in the DT.

In case of missing regulator nodes in DT, pdata->regulators will be
populated with all the regulators but their init_data will be NULL.
