remoteproc: qcom: q6v5: Update running state before requesting stop
commit5.4-rM2-2.2.x-imx-squashed5b7be88007
upstream. Sometimes the stop triggers a watchdog rather than a stop-ack. Update the running state to false on requesting stop to skip the watchdog instead. Error Logs: $ echo stop > /sys/class/remoteproc/remoteproc0/state ipa 1e40000.ipa: received modem stopping event remoteproc-modem: watchdog received: sys_m_smsm_mpss.c:291:APPS force stop qcom-q6v5-mss 4080000.remoteproc-modem: port failed halt ipa 1e40000.ipa: received modem offline event remoteproc0: stopped remote processor 4080000.remoteproc-modem Reviewed-by: Evan Green <evgreen@chromium.org> Fixes:3b415c8fb2
