Subject: [PATCH 4/9] regulator/core: regulator_bulk_get: remove redundant NULL
 stores

On error, callers of regulator_bulk_get() pass the error up and don't
use the pointers in consumers[]. The function is documented to release
all regulators if any request fails.

Note: if an i-th regulator_get() failed only the i-th pointer was
cleared. This is another suggestion that the clearing was unnecessary.
