 4Description:
 5		The /sys/devices/.../waiting_for_supplier attribute is only
 6		present when fw_devlink kernel command line option is enabled
 7		and is set to something stricter than "permissive".  It is
 8		removed once a device probes successfully (because the
 9		information is no longer relevant). The number read from it (0
10		or 1) reflects whether the device is waiting for one or more
11		suppliers to be added and then linked to using device links
12		before the device can probe.
13
14		A value of 0 means the device is not waiting for any suppliers
15		to be added before it can probe.  A value of 1 means the device
16		is waiting for one or more suppliers to be added before it can
17		probe.
