Subject[PATCH] init/do_mounts: Add create_dev() failure log
Date
if create_dev() function fails to create the root mount device (/dev/root),
then it goes to panic as root device not found but there is no check/log
present in case of failure, So i have added the log in case it fails to create
the root device. It will help in debugging.
