Cyril Brulebois d85944d107 Mention pr_info() rather than KERN_INFO
The latter might have been used along with printk() in an earlier
version, but pr_info() is getting used consistently so adjust the
#include comments accordingly.

For the avoidance of doubt, pr_info() actually comes from printk.h,
which gets #include'd by kernel.h.
