Thus I would expect that the passed pointer will usually be still valid. (Can the proposed null pointer check be omitted then?) How do you think about the following change possibility? +err_release_channel: + dma_release_channel(owl_host->dma); Would you like to add the tag “Fixes” to the change description? Regards, Markus
