If SATA_HOST is n, build fails:

drivers/scsi/hisi_sas/hisi_sas_main.o: In function `hisi_sas_fill_ata_reset_cmd':
hisi_sas_main.c:(.text+0x2500): undefined reference to `ata_tf_to_fis'

Select SATA_HOST to fix this.

That's not right. SATA_HOST was only introduced recently in the ATA 
code. It would fix those kconfig changes.

That does not feel right.

SCSI_HISI_SAS depends on ATA, but SATA_HOST also depends on ATA, so it 
seems better to just depend on SATA_HOST (and omit explicit ATA 
dependency), rather than select it.

Thanks,
John

Depends on SATA_HOST will result int this:

scripts/kconfig/mconf  Kconfig
drivers/scsi/hisi_sas/Kconfig:2:error: recursive dependency detected!
drivers/scsi/hisi_sas/Kconfig:2:        symbol SCSI_HISI_SAS depends on SATA_HOST
drivers/ata/Kconfig:37: symbol SATA_HOST is selected by SCSI_SAS_ATA
drivers/scsi/libsas/Kconfig:18: symbol SCSI_SAS_ATA depends on SCSI_SAS_LIBSAS
drivers/scsi/libsas/Kconfig:9:  symbol SCSI_SAS_LIBSAS is selected by SCSI_HISI_SAS
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"


All users of SATA_HOST have the 'select' statement, so we should do the same here.

Sorry for missing hisi_sas and thanks for fixing it.

Yes, this should be:

SATA_HOST config option is invisible to user so it needs to be
selected.

PS I have audited all drivers dependent on ATA again and this is
the only driver needing fixing.
