Subject: Re: [PATCH 2/2] vsprintf: remove redundant and unused %pCn format specifier

Quoting Luca Ceresoli (2025-03-07 03:19:08)
> %pC and %pCn print the same string, and commit 900cca294425 ("lib/vsprintf:
> add %pC{,n,r} format specifiers for clocks") introducing them does not
> clarify any intended difference. It can be assumed %pC is a default for
> %pCn as some other specifiers do, but not all are consistent with this
> policy. Moreover there is now no other suffix other than 'n', which makes a
