During the process of driver probing, the probe function should return < 0 for failure, otherwise, the kernel will treat value > 0 as success. Since this is a bug rather than a recoverable runtime error we should use dev_alert() instead of dev_err().

Always disabling NCQ for Samsung 860/870 SSDs regardless of the host SATA adapter vendor will cause I/O performance degradation with well behaved adapters. To limit the performance impact to ATI adapters, introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ only for these adapters. Also, two libata.force parameters (noncqati and ncqati) are introduced to disable and enable the NCQ for the system which equipped with ATI SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ function to be enabled or disabled according to the demand. After verifying the chipset from the user reports, the issue appears on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on recent AMD SATA adapters. The vendor ID of ATI should be 0x1002. Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to ATA_HORKAGE_NO_NCQ_ON_ATI.

But there is a large number of users which is still reporting issues with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or Marvell SATA controllers and all reporters also report these problems going away when disabling queued trims. Note that with AMD SATA controllers users are reporting even worse issues and only completely disabling NCQ helps there, this will be addressed in a separate patch.

If enabling the feature fails, it is because the device does not support NCQ priority. Otherwise, the feature is enabled and success indicates that the device supports NCQ priority. Improve this odd interface by introducing the read-only ncq_prio_supported sysfs device attribute to indicate if a SATA device supports NCQ priority. The value of this attribute reflects the status of device flag ATA_DFLAG_NCQ_PRIO, which is set only for devices supporting NCQ priority. Add this new sysfs attribute to the device attributes group of libahci and libata-sata.
