Subject: ahci: fix AHCI parameters not taken into account
From: Antoine Tenart <antoine.tenart@xxxxxxxxxxxxxxxxxx>
commit 9a23c1d6f0f5dbac4c9b73fa6cea7c9ee3d29074 upstream.
Changes into the AHCI subsystem have introduced a bug by not taking into
account the force_port_map and mask_port_map parameters when using the
ahci_pci_save_initial_config function. This commit fixes it by setting
the internal parameters of the ahci_port_priv structure.
