Subject: perf check-headers.sh: Simplify arguments passing
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=15019e9815a06b84870bfaf9ee1e8b75bf7ef6a6;p=linux.git

perf check-headers.sh: Simplify arguments passing

Passing whole string instead of parsing them after.  It simplifies
things for the next patches, that adds another function call, which
makes it hard to pass arguments in the correct shape.
