|
|
* objects removes the previous ordering that was set between the
|
|
* same set of spi objects. This is verified by invoking
|
|
* unsetOrdering() method twice consecutively with respect to the same
|
|
* spi objects and unsetOrdering() is supposed to return false when
|
|
* called for the second time.
