From 9dfd005a3f4e1c648cb4aa1dc70604bb370c5e7b Mon Sep 17 00:00:00 2001 From: Michael Hudson-Doyle Date: Thu, 31 Oct 2013 16:47:45 -0700 Subject: [PATCH] perf tools: Remove cast of non-variadic function to variadic commit 53805eca3d89b095062c11a6798689bb0af09216 upstream. The 4fb71074a570 (perf ui/hist: Consolidate hpp helpers) cset introduced a cast of percent_color_snprintf to a function pointer type with varargs. Change percent_color_snprintf to be variadic and remove the cast. The symptom of this was all percentages being reported as 0.00% in perf report --stdio output on the armhf arch.
