[PATCH v2 0/2] regulator: of: Fixes to of_regulator_bulk_get_all()

[Alexey Charkov]

of_regulator_bulk_get_all() only fills in the .consumer part of the
struct regulator_bulk_data for the regulators it gets, leaving .supply as
garbage, while the rest of the regulator core expects a meaningful name
there (e.g. for error prints), causing uninitialized memory access in any
failure paths in the core.

It also allocates the supplies array and hands it to callers, but never
says the callers need to free it (which they don't currently), causing
leaks.

Fix the former and document the latter in the kerneldoc to help any new
users avoid the leak.
