Subject: [PATCH 5.15 73/83] perf parse-events: Add const to evsel name
From: Ian Rogers <irogers@...gle.com>
[ Upstream commit 8e8bbfb311a26a17834f1839e15e2c29ea5e58c6 ]
The evsel name is strdup-ed before assignment and so can be const.
A later change will add another similar string.
Using const makes it clearer that these are not out arguments.
