Ekansh Gupta 5e305b5986 misc: fastrpc: Restrict untrusted app to attach to privileged PD ... commit bab2f5e8fd upstream. Untrusted application with access to only non-secure fastrpc device node can attach to root_pd or static PDs if it can make the respective init request. This can cause problems as the untrusted application can send bad requests to root_pd or static PDs. Add changes to reject attach to privileged PDs if the request is being made using non-secure fastrpc device node.
