Alex Elder f5c2be9e9b greybus: connection: check for duplicate cport ids Check at connection creation time for an attempt to create a connection with an interface CPort ID that's the same as one that's already been created. Define a new helper function to look for such a duplicate. The check for a duplicate is only performed at initialization time, and CPorts are initialized serially for each bundle, so there's no need to acquire the list lock for this search.

Alex Elder f5c2be9e9b greybus: connection: check for duplicate cport ids

Check at connection creation time for an attempt to create a
connection with an interface CPort ID that's the same as one that's
already been created.

Define a new helper function to look for such a duplicate.  The
check for a duplicate is only performed at initialization time,
and CPorts are initialized serially for each bundle, so there's
no need to acquire the list lock for this search.
