Subject: [libata] sata_sis: use correct S/G table size
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=96af154710d44b574515431a0bb014888398a741;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[libata] sata_sis: use correct S/G table size

sata_sis has the same restrictions as other SFF controllers, and so must
use LIBATA_MAX_PRD to denote that SCSI may only fill ATA_MAX_PRD/2
entries, due to our need to handle IOMMU merging.
