It is sometimes useful to know that a device is on the deferred probe list rather than, say, not having a driver available. Expose this information to user-space. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

What: /sys/devices/.../deferred_probe

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.
