From: Sasha Levin <sashal@kernel.org>

Also in:
linux-mmc, lkml, stable
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, secure digital host controller interface (sdhci) nxp i.mx driver, the rest · Maintainers:
Ulf Hansson, Adrian Hunter, Haibo Chen, Linus Torvalds
From: Haibo Chen <haibo.chen@nxp.com>
[ Upstream commit 1194be8c949b8190b2882ad8335a5d98aa50c735 ]
According the RM, the bit[6~0] of register ESDHC_TUNING_CTRL is
TUNING_START_TAP, bit[7] of this register is to disable the command
CRC check for standard tuning. So fix it here.
