Subject[PATCH v4 11/14] perf evsel: Make evsel__env always return a valid env
From
From: Kim Phillips <kim.phillips@amd.com>

It's possible to have an evsel and evsel->evlist populated without
an evsel->evlist->env, when, e.g., cmd_record is in its error path.

Future patches will add support for evsel__open_strerror to be able
to customize error messaging based on perf_env__{arch,cpuid}, so
let's have evsel__env return &perf_env instead of NULL in that case.
