Subject: um: Use printk instead of printf in make_uml_dir
X-Git-Tag: v4.13-rc1~8^2~14
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e03c78ac2d7709b7556a9b8dd584e2969c6fce67;p=karo-tx-linux.git

um: Use printk instead of printf in make_uml_dir

Since this function will be called after printk buffer
initialized, use printk as other functions do.
