0004 Description:
0005 The /sys/devices/.../waiting_for_supplier attribute is only
0006 present when fw_devlink kernel command line option is enabled
0007 and is set to something stricter than "permissive". It is
0008 removed once a device probes successfully (because the
0009 information is no longer relevant). The number read from it (0
0010 or 1) reflects whether the device is waiting for one or more
0011 suppliers to be added and then linked to using device links
0012 before the device can probe.
0013
0014 A value of 0 means the device is not waiting for any suppliers
0015 to be added before it can probe. A value of 1 means the device
0016 is waiting for one or more suppliers to be added before it can
0017 probe.
