[SCSI] aic79xx: use tcq functions (0aa800db) · Commits · 戴 / test

This patch converts aic79xx to use the midlayer-supplied tcq functions. We also set the queuedepth to '1' if tcq is disabled; the aic79xx driver gets confused otherwise. Will set it back to '2' once I figure out how to queue requests in the driver. Signed-off-by:
