Subject: perf session: Don't write to memory pointed to a const pointer
X-Git-Tag: v7.0-rc1~16^2~109
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f1321cce848c558fde4c0c6bcd5e53f3cefd3af2;p=thirdparty%2Flinux.git

perf session: Don't write to memory pointed to a const pointer

Since it is freshly allocated just attribute it to a non-const pointer
and then change it via that pointer.

That way we avoid const-correctness warnings in recent glibc versions.
