sys/dev/ic : ahci.c
Log message:
Some HABs reset parts of AHCI_PREG_CMD when AHCI_PREG_SCTL_DET_INIT
gets set. Therefore, ahci_port_softreset() restores the sate of the
former register once the device detection sequence is finished. The
device detection code in ahci_pmp_port_portreset() does not restore
AHCI_PREG_CMD afterwards, so let it catch up. Apparently, this part
was an oversight as ahci_pmp_port_portreset() did not otherwise use
"cmd".
