From a84ca704d8306a949578d36c028c8e1bab3dcf0b Mon Sep 17 00:00:00 2001 From: Haowen Bai Date: Sun, 24 Apr 2022 16:26:41 +0800 Subject: [PATCH] selftests/powerpc/pmu: Fix unsigned function returning negative constant The function __perf_reg_mask has an unsigned return type, but returns a negative constant to indicate an error condition. So we change unsigned to int.
