remoteproc: Fix sysfs interface to stop a suspended processor Commit 2aefbef04149 ("remoteproc: Add a sysfs interface for firmware and state") has added an interface to be able to stop a remote processor, change the firmware and start the remote processor using the new firmware through the sysfs files 'state' and 'firmware'. Any firmware change requires the processor to be in a stopped state. The logic in 'stop' checks for a valid state (RPROC_RUNNING) before a processor can be stopped. A booted remote processor though can also be in RPROC_SUSPENDED state if the driver controlling the device supports runtime auto-suspend, and any attempt to stop such a processor throws an error, "write error: Invalid argument". It should be possible to stop a processor that is in suspended state using the sysfs entry, as this is a perfectly functional scenario when either removing the module, or unbinding the device from the driver. Fix the sysfs logic to permit the same. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Suman Anna <s-anna@ti.com>
