[PATCH v3 06/15] rpmsg: update rpmsg_chrdev_register_device function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As driver is now the rpmsg_ioctl, rename the function.
In addition, to avoid probe issue related to module dependency,
move the function in the rpmsg_ctrl module. This ensure that the
rpmsg_ctrl module is loaded before that the device is created.
