dmaengine: dmatest: Restore default for channel
In case of dmatest is built-in and no channel was configured test doesn't run with: dmatest: Could not start test, no channels configured Even though description to "channel" parameter claims that default is any. Add default channel back as it used to be rather than reject test with no channel configuration. Fixes: d53513d5dc285d9a95a534fc41c5c08af6b60eac ("dmaengine: dmatest: Add support for multi channel testing) Reported-by: Dijil Mohan <Dijil.Mohan@arm.com> Signed-off-by: Vladimir Murzin <vladimir.murzin@arm.com> Link: https://lore.kernel.org/r/20200429071522.58148-1-vladimir.murzin@arm.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
