Subject: perf report: Use ui__warning in some more places
X-Git-Tag: v3.1-rc2~25^2~4^2
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=00894ce9b85887caa0c16e18757004b9cc9f64cf;hp=3e9f45a7a4179604ccbae1589de0e7165bc6fcd0

perf report: Use ui__warning in some more places

So that we get a proper warning in the TUI in cases like:

 $ perf report --stdio -g fractal,0.5,caller --sort pid
 Selected -g but no callchain data. Did you call 'perf record' without -g?
 $

The --stdio case is ok because it uses fprintf, ui__warning is needed to
figure out if --stdio or --tui is being used.
