Subject: [PATCH v2 1/2] extcon: max77693: add device-tree compatible string
Commit 57f706bf7307 ("ARM: dts: samsung: exynos4412-midas: add USB
connector and USB OTG") added a 'muic' node to the MAX77693 PMIC
definition in various device-tree files. Since that commit, the newly
created MFD cell gained its own of_node and compatible string. This
changed its modalias, what in turn broke automated loading of the driver
module, because the new modalias is based on the of_node compatible
string, not the platform device name.
Fix this by adding the needed device-tree compatible string.
