From: Niklas Cassel <cassel@xxxxxxxxxx>
commit 1066fe825987da007669d7c25306b4dbb50bd7dd upstream.
We got another report that CT1000BX500SSD1 does not work with LPM.
If you look in libata-core.c, we have six different Crucial devices that
are marked with ATA_HORKAGE_NOLPM. This model would have been the seventh.
(This quirk is used on Crucial models starting with both CT* and
Crucial_CT*)
It is obvious that this vendor does not have a great history of supporting
LPM properly, therefore, add the ATA_HORKAGE_NOLPM quirk for all Crucial
BX SSD1 models.
Fixes: 7627a0edef54 ("ata: ahci: Drop low power policy board type")
