Alex Elder deb4b9efb3 greybus: add a reference to pending operations Grab an extra reference to an operation before sending it. Drop that reference at the end of its completion handling. It turns out gb_operation_get() got deleted along the way, so this re-introduces it. We're assuming we only get a reference when there's at least one in existence so we don't need a semaphore to protect it. Emphasize this by not returning a pointer to the referenced operation.

Alex Elder deb4b9efb3 greybus: add a reference to pending operations

Grab an extra reference to an operation before sending it.  Drop
that reference at the end of its completion handling.

It turns out gb_operation_get() got deleted along the way, so this
re-introduces it.  We're assuming we only get a reference when
there's at least one in existence so we don't need a semaphore to
protect it.  Emphasize this by *not* returning a pointer to
the referenced operation.
