regulator: Return actual error in of_regulator_bulk_get_all()
[ Upstream commit 395a41a1d3e377462f3eea8a205ee72be8885ff6 ]
If regulator_get() in of_regulator_bulk_get_all() returns an error, that
error gets overridden and -EINVAL is always passed out. This masks probe
deferral requests and likely won't work properly in all cases.
Fix this by letting of_regulator_bulk_get_all() return the original
error code.
