[PATCH v6 01/16] PCI: rzg3s-host: Fix reset handling in probe error path
From: John Madieu <john.madieu.xa@bp.renesas.com>

Fix incorrect reset_control_bulk_deassert() call in the probe error
path. When unwinding from a failed pci_host_probe(), the configuration
resets should be asserted to restore the hardware to its initial state,
not deasserted again.
