mainline inclusion from mainline-v6.4-rc1 commit 25d8c25025a4 category: cleanup bugzilla: https://gitee.com/openeuler/kernel/issues/I77IH6 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
"pmu->name" is initialized by perf_pmu_register() function, so remove the redundant initialized in hisi_pmu_init().
