Description LeoLiu-oc zhaoxin_group 2025-12-23 14:28:32 UTC 
This reverts commit dd3a735e710fe1d5f65be1c080bcb708a9c397e0.
a977d11b7f64 ("ata: libata: disallow dev-initiated LPM transitions to unsupported states") has introduced 
	if (!(hpriv->cap & HOST_CAP_PART))
		host->flags |= ATA_HOST_NO_PART;

	if (!(hpriv->cap & HOST_CAP_SSC))
		host->flags |= ATA_HOST_NO_SSC;

	if (!(hpriv->cap2 & HOST_CAP2_SDS))
		host->flags |= ATA_HOST_NO_DEVSLP;
Currently, the relevant code is duplicated, so it needs to be withdrawn.
