Subject: remoteproc: Calculate max_notifyid during load
X-Git-Tag: v4.14-rc1~2351^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b35d7afc3ba9d5cf28655481aef1dd6a01c6421d;p=platform%2Fkernel%2Flinux-rpi.git

remoteproc: Calculate max_notifyid during load

The calculation of max_notifyid must only be done before we call start()
on the remoteproc drivers, so move the calculation to be part of the
loading steps.
