----------------------------------------------------------------------

This change fixes the checkpatch warning described in
commit cbacb5ab ("docs: printk-formats: Stop encouraging use of

Standard integer promotion is already done and %hx and %hhx is useless so
do not encourage the use of %hh[xudi] or %h[xudi].
