Revision 5040ab67a2c6d5710ba497dc52a8f7035729d7b0 authored by Tejun Heo on 11 January 2010, 02:14:44 UTC, committed by Jeff Garzik on 12 January 2010, 19:34:14 UTC
Interestingly, when SIDPR is used in ata_piix, writes to DET in
SControl sometimes get ignored leading to detection failure.  Update
sata_link_resume() such that it reads back SControl after clearing DET
and retry if it's not clear.
