From 2b17b8d7cc65d333a48c6d32ee44fc489cecb7d9 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 18 May 2020 15:09:39 +0300 Subject: [PATCH] mmc: sdhci: Fix SDHCI_QUIRK_BROKEN_CQE Previous to commit 511ce378e16f07 ("mmc: Add MMC host software queue support"), removing MMC_CAP2_CQE was enough to disable command queuing, but now the cqe_ops must also be NULL otherwise ->cqe_enable() will be called. Fix SDHCI_QUIRK_BROKEN_CQE to do that.
