From e1f5633ad4ddcef37a6dc9a5a64159978c0f7a22 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 1 Dec 2014 15:51:17 +0200 Subject: [PATCH] mmc: sdhci-acpi: Add SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC 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.
