The `role` member of `struct virtio_device` stores either the value VIRTIO_DEV_DRIVER or VIRTIO_DEV_DEVICE. This means the function rpmsg_virtio_get_role() will also return one of these values. The values RPMSG_HOST and RPMSG_REMOTE are defined to be the same, but there is no need for this redefinition. Update the return values in the comment docs. While here, remove the same from rpmsg_virtio_set_wait_cb() which does not return anything, this looks to be a copy/paste error. Signed-off-by: Andrew Davis <afd@ti.com>
For all cases when the role is checked in rpmsg_virtio, what is being checked is the role of the underlying virtio layer. As such, we should be matching against the role definitions for the virtio layer (VIRTIO_DEV_DEVICE and VIRTIO_DEV_DRIVER). Fix this here. While the underlying virtio layer may be asymmetric, the RPMSG layer generally is symmetrical. There is no need to define a HOST or REMOTE role specific to the RPMSG layer. And as there are now no more internal users of these definitions, deprecate them here. Signed-off-by: Andrew Davis <afd@ti.com>
Now that we match role to VIRTIO_DEV_{DRIVER,DEVICE} we can replace
all these double check if statements with the role checking macro
already used in all other files.
