dmaengine: avoid non-constant format string
Using an arbitrary string as a printf-style format can be a security problem if that string contains % characters, as the optionalal -Wformat-security flag points out: drivers/dma/dmaengine.c: In function '__dma_async_device_channel_register': drivers/dma/dmaengine.c:1073:17: error: format not a string literal and no format arguments [-Werror=format-security] 1073 | dev_set_name(&chan->dev->device, name); | ^~~~~~~~~~~~ Change this newly added instance to use "%s" as the format instead to pass the actual name.
