[PATCH 03/13] tools/power turbostat: Fix unrecognized option '-P'

From: Len Brown

Date: Sat Apr 25 2026 - 14:48:13 EST


From: David Arcari <darcari@xxxxxxxxxx>

The '-P' short option (shorthand for --no-perf) is not present in the
optstring of the second call to getopt_long_only(). This results in
the "unrecognized option" error when the tool reaches the main parsing
loop.

Add 'P' to the second getopt_long_only() call to ensure it is
consistently recognized.

Fixes: a0e86c90b83c ("tools/power turbostat: Add --no-perf option")
