[PATCH] perf/x86/intel: constify array lbr_desc and make a function static

From: Colin King
Date: Thu Jun 29 2017 - 05:14:54 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

A few minor clean-ups: constify array lbr_desc and make local
function lbr_from_signext_quirk_rd static to fix sparse warning:

"symbol 'lbr_from_signext_quirk_rd' was not declared. Should it be static?"
