Subject: ftrace: enable format arguments checking
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3ddeb912f41801fd1968c7880d031702a396e4d0;p=linux-beck.git

ftrace: enable format arguments checking

Impact: broaden gcc printf format checks for ftrace_printk()

format arguments checking for ftrace_printk() is __printf(1, 2),
not __printf(1, 0).
