Subject: lib/vsprintf.c: consume 'p' in format_decode
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ffbfed03b4bdd229b99c2611f5ace1fbc912caaa;p=linux-beck.git

lib/vsprintf.c: consume 'p' in format_decode

It seems a little simpler to consume the p from a %p specifier in
format_decode, just as it is done for the surrounding %c, %s and %% cases.

While there, delete a redundant and misplaced comment.
