Subject: [PATCH] PCI/pwrctrl: generic: Fix leaking array from
 of_regulator_bulk_get_all()

of_regulator_bulk_get_all() allocates the consumers array and returns it to
the caller, who is expected to free it at an appropriate time.  PCI pwrctrl
never did, leading to a memory leak.

Add an explicit kfree() for the consumers array.
