From db6e8cdfcde84be556baa6d6b2424668ca21a36c Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 1 Dec 2014 15:51:16 +0200 Subject: [PATCH] mmc: sdhci-pci: Add SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC to BYT SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC actually causes standard-compliant behaviour by causing the flagging of the last DMA transfer descriptor as the end instead of there being an additional nop descriptor which is flagged as the end. Consequently, it is better to have the quirk. Add it for BYT.
