Create the rpmsg_ctrl.c module and move the code related to the rpmsg_ctrldev device in this new module. Add the dependency between rpmsg_char and rpmsg_ctrl in the kconfig file: 1) RPMSG_CTRL can set as module or built-in if RPMSG=y || RPMSG_CHAR=y || RPMSG_CHAR=n 2) RPMSG_CTRL can not be set as built-in if RPMSG=m || RPMSG_CHAR=m Note that RPMGH_CHAR and RPMSG_CTRL can be activated separately. Therefore, the RPMSG_CTRL configuration must be set for backwards compatibility.
