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.
Fixes: 10b8e0fd3f72 ("dmaengine: add channel device name to channel registration")
