Re: [PATCH] perf annotate: Fix build with NO_SLANG=1

["Li, Tianyou" <tianyou.li@intel.com>]

Hi Namhyung,

My bad. Thanks for taking time to fix this. I've tested with my ICX box 
with and without the patch. I can confirm the issue reproduced and fixed 
by your patch, tested through 'make NO_SLANG=1'. Sorry about the 
inconvenience. Thanks.

Regards,

Tianyou
