From 880f5b388252fedb26c70bb80ad1d7c8abbc0607 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Mon, 30 Oct 2017 23:11:14 -0700 Subject: remoteproc: Pass type of shutdown to subdev remove remoteproc instances can be stopped either by invoking shutdown or by an attempt to recover from a crash. For some subdev types it's expected to clean up gracefully during a shutdown, but are unable to do so during a crash - so pass this information to the subdev remove functions.
