From: Bhaumik Bhatt <bbhatt@xxxxxxxxxxxxxx> [ Upstream commit 4e44ae3d6d9c2c2a6d9356dd279c925532d5cd8c ] If a channel was explicitly stopped but not reset and a driver remove is issued, clean up the channel context such that it is reflected on the device. This move is useful if a client driver module is unloaded or a device crash occurs with the host having placed the channel in a stopped state.
