+Subject: [PATCH 17/27] mmc: read mmc alias from device tree
+
+To get the SD/MMC host device ID, read the alias from the device
+tree.
+
+This is useful in case a SoC has multipe SD/MMC host controllers while
+the second controller should logically be the first device (e.g. if
+the second controller is connected to an internal eMMC). Combined
+with block device numbering using MMC/SD host device ID, this
+results in predictable name assignment of the internal eMMC block
+device.
