Subject: ARM: 8352/1: perf: Fix the pmu node name in warning message
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b8786ff7a1b31645ae2c26a2ec32dbd42ac1094;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: 8352/1: perf: Fix the pmu node name in warning message

With commit 9fd85eb502a7 ("ARM: pmu: add support for interrupt-affinity
property"), we print a warning when we find a PMU SPI with a missing
missing interrupt-affinity property in a pmu node. Unfortunately, we
pass the wrong (NULL) device node to of_node_full_name, resulting in
unhelpful messages such as:

 hw perfevents: Failed to parse <no-node>/interrupt-affinity[0]

This patch fixes the name to that of the pmu node.

Fixes: 9fd85eb502a7 (ARM: pmu: add support for interrupt-affinity property)
