This patch refines ahci_kick_engine() after discussion with Tejun about FBS(FIS-based switching) support preparation: a. Kill @force_restart and always kick the engine. The only case where @force_restart is zero is when it's called from ahci_p5wdh_hardreset() Actually at that point, BSY is pretty much guaranteed to be set. b. If PMP is attached, ignore busy and always do CLO. (AHCI-1.3 9.2) Signed-off-by:
