Merge tag 'printk-for-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Add upper case flavor for printing MAC addresses (%p[mM][U]) and use
   it in the nintendo driver

 - Fix matching of hash_pointers= parameter modes

 - Fix size check of vsprintf() field_width and precision values

 - Add check of size returned by vsprintf()

 - Add KUnit test for restricted pointer printing (%pK)

 - Some code cleanup
