+Description:	Read-only. Returns a string describing the failure
+		of a secure update. This string will be in the form
+		of <STATUS>:<ERROR>, where <STATUS> will be one of
+		the status strings described for the status sysfs
+		file and <ERROR> will be one of the following:
+		hw-error, timeout, user-abort, device-busy,
+		invalid-file-size, read-write-error, flash-wearout,
+		file-read-error.  The error sysfs file is only
+		meaningful when the secure update engine is in the
+		idle state. If this file is read while a secure
+		update is in progress, then the read will fail with
+		EBUSY.
