Subject: [PATCH] ahci: fix AHCI parameters not taken into account
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.
Fixes: 725c7b570fda
