+Subject: [PATCH 34/93] mmc: fsl_esdhc: add workaround for non-removable card
+ of esdhc-2
+
+The esdhc-2 usually uses some on-board memory devices such as eMMC
+card or SDIO wifi module, and it doesn't support SDHC_CD_B. So we
+could only assume it always has a card instead of detecting SDHC_CD_B
+status. This patch is to add workaround for these non-removable
+cards which are used by esdhc-2.
