+What: /sys/devices/.../deferred_probe
+Date: August 2016
+Contact: Ben Hutchings <ben.hutchings@codethink.co.uk>
+Description:
+ The /sys/devices/.../deferred_probe attribute is
+ present for all devices. If a driver detects during
+ probing a device that a related device is not yet
+ ready, it may defer probing of the first device. The
+ kernel will retry probing the first device after any
+ other device is successfully probed. This attribute
+ reads as 1 if probing of this device is currently
+ deferred, or 0 otherwise.
