2026-09-21	ata: libata-core: Extend Samsung LPM quirk to AMD controllers	Niklas Cassel
	A Samsung SSD 870 QVO 8TB connected to an AMD 600 Series chipset SATA controller is reported to time out on STANDBY IMMEDIATE during system suspend with med_power_with_dipm enabled. The command completes when using max_performance instead. The existing Samsung LPM quirk only matches ATI controllers, leaving AMD controllers unaffected. Rename it to ATA_QUIRK_NO_LPM_ON_ATI_AND_AMD and extend the vendor check to AMD for the same Samsung SSD model patterns. Keep LPM behavior unchanged for other controller vendors, including Intel. Leave ATA_QUIRK_NO_NCQ_ON_ATI restricted to ATI, since the reported AMD issue concerns LPM rather than NCQ.

2026-09-16	ata: libata-scsi: fix ata_dsm_trim_pages() kernel-docgrafted	Niklas Cassel
	make htmldocs fails with: Documentation/driver-api/libata:604: ./drivers/ata/libata-scsi.c:2301: ERROR: Unexpected indentation. [docutils] The Return: section of ata_dsm_trim_pages() ends its first sentence with a colon and continues with an indented bullet list. reStructuredText requires a blank line before an indented block, so docutils chokes on the list. Simply adding the missing blank line does not work either: Return: is a kernel-doc "special section", which is terminated by the first blank line, so the bullet list would end up in the Description section, detached from the sentence introducing it. Spell the two bounds out as prose instead, so that the Return: section stays self-contained. Documentation-only change.
