remoteproc is writing '\0' in the shared mem region. This region is shared among multiple clients that are also trying to read. Hence they miss first character. Remove this null character write, as this mem area is supposed to be Read only. Further during every subsystem reboot, this region is initialized with default, hence no need to write this region.
