Subject: [PATCH v2 2/8] mmc: sdhci-esdhc-imx: usdhc does not have missing card interrupt issue
Date: Mon, 22 Sep 2014 17:12:05 +0800	[thread overview]
Message-ID: <1411377131-19741-3-git-send-email-b29396@freescale.com> (raw)
In-Reply-To: <1411377131-19741-1-git-send-email-b29396@freescale.com>

The usdhc does not have missing card interrupt issue, so execute the
workaround conditionally.
