From 608d792192d7136d354bc1b44585c441164dc54e Mon Sep 17 00:00:00 2001 From: Sarangdhar Joshi Date: Mon, 23 Jan 2017 17:53:18 -0800 Subject: [PATCH] remoteproc: Add RPROC_DELETED state Add new state RPROC_DELETED to handle synchronization between rproc_del() and other operations on rproc. This state represents the rproc device that has been "deleted".
