Having a list of descriptors allocated for the channel at device_alloc_chan_resources() time is a sign for bad free usage. Return err and add a debug message in case the channel is not free from a previous use. atchan->descs_allocated becomes useless, get rid of it. More, drop the error message in atc_desc_get() because now it would introduce an extra if statement. The callers of atc_desc_get() already print error messages in case the callee fails, no one is hurt. Signed-off-by:
