Subject: [PATCH 2/7] x86: de-duplicate sub-architecture strings accumulation
Date: Thu, 30 Jun 2022 14:53:35 +0200 [thread overview]
Message-ID: <736c0fe5-af5d-9d2d-d518-d5b3ccf8a4b8@suse.com> (raw)
In-Reply-To: <01f502ff-5b51-86d3-ed54-646df7d22037@suse.com>
Introduce a helper function to replace 4 instances of similar code. Use
reconcat() to cover the previously explicit free() (which really should
have been xfree() anyway).
