From: Suman Anna <s-anna@xxxxxx> Commit e88dae5da46d ("rpmsg: Move virtio specifics from public header") has moved the struct rpmsg_hdr definition from the public rpmsg.h and made it private to virtio_rpmsg_bus module. This structure is a common header used in all virtio rpmsg messages, and used by various virtio rpmsg bus drivers. So, move this back into the virtio_rpmsg specific public header to make it visible to various rpmsg drivers.
