Since commit4dffed5b3a("rpmsg: Name rpmsg devices based on channel id"), it is no more possible for a firmware to register twice a service (on different endpoints). rpmsg_register_device function is failing when calling device_add for the second time as second device has the same name as first one already register. It is because name is based only on service name and so is not more unique. Previously name was unique thanks to the use of rpmsg_dev_index. This patch adds destination and source endpoint numbers device name to create an unique identifier.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
