Subject[RFC PATCH v2 1/6] um: Use printk instead of printf in make_uml_dir
Date
Since this function will be called after printk buffer
initialized, use printk as other functions do.

Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org>
---
Changes in v2:
- Use "%s", __func__ according to checkpatches.pl
