To be precise, the above commit was fine because it was the last
"case" in "switch". It has got broken by the commit
7b1924a1d930eb2 ("vsprintf: add printk specifier %px").

Other than that the patch fixes a real problem. I have updated the "Fixes"
tag, added stable tag and pushed it into printk.git, for-4.19 branch.
