It does:
| Subject: [PATCH] sis5513: fix PIO setup for ATAPI devices
|
| Clear prefetch setting before potentially (re-)enabling it in
| config_drive_art_rwp() so the transition of the device type on
| the port from ATA to ATAPI (i.e. during warm-plug operation)
| is handled correctly.
and the empty port defaults to ATA-like behavior for the initial PIO setup.
