4da6d6475SSaravana KannanDescription:
5da6d6475SSaravana Kannan		The /sys/devices/.../waiting_for_supplier attribute is only
6da6d6475SSaravana Kannan		present when fw_devlink kernel command line option is enabled
7da6d6475SSaravana Kannan		and is set to something stricter than "permissive".  It is
8da6d6475SSaravana Kannan		removed once a device probes successfully (because the
9da6d6475SSaravana Kannan		information is no longer relevant). The number read from it (0
10da6d6475SSaravana Kannan		or 1) reflects whether the device is waiting for one or more
11da6d6475SSaravana Kannan		suppliers to be added and then linked to using device links
12da6d6475SSaravana Kannan		before the device can probe.
13da6d6475SSaravana Kannan

16da6d6475SSaravana Kannan		is waiting for one or more suppliers to be added before it can
17da6d6475SSaravana Kannan		probe.
