Subject: tools/power/x86/intel-speed-select: Fix output when running on unsupported CLX platforms
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1b25f03f3daf7c26c37050a7b2b5858ad5f99cfc;p=thirdparty%2Fkernel%2Flinux.git

tools/power/x86/intel-speed-select: Fix output when running on unsupported CLX platforms

When running intel-speed-select on unsupported CLX platforms, it prints
 intel-speed-select: Invalid CPU model (85)
 : Success
Because this is not a system error and errno is not set.

Replace err() with exit().
