The same goes for the next patch.

Function prototypes have to match with rpmsg_endpoint_ops structure defined below. So seems to me not possible to just rename the functions.

So replace them with rproc_ops::sendto() and rproc_ops::trysendto() where the destination address would be ingnored. > > > The same goes for the next patch.

Implement the sendto ops to support the future rpmsg_char update for the vitio backend support. The use of sendto in rpmsg_char is needed as a destination address is requested at least by the virtio backend. The glink implementation does not need a destination address so ignores it.
