Subject: [PATCH 5.15 77/83] perf tools: Check vmlinux/kallsyms arguments in all tools
Date:   Mon,  3 Oct 2022 09:11:42 +0200

From: James Clark <james.clark@arm.com>

[ Upstream commit 7cc72553ac03ec20afe2dec91dce4624ccd379b8 ]

Only perf report checked the validity of these arguments so apply the
same check to all tools that read them for consistency.
