Subject: lib/vsprintf.c: implement printf() in terms of vprintf()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=97587786463ae3a44c95fcb053ab27136c646aa3;p=u-boot.git

lib/vsprintf.c: implement printf() in terms of vprintf()

This saves some code, both in terms of #LOC and .text size, and it is
also the normal convention that foo(...) is implemented in terms of
vfoo().
