Subject: [PATCH 01/23] hw/ppc/e500: Do not leak struct boot_info
Date: Mon, 23 Sep 2024 11:29:54 +0200 [thread overview]
Message-ID: <20240923093016.66437-2-shentey@gmail.com> (raw)
In-Reply-To: <20240923093016.66437-1-shentey@gmail.com>
The struct is allocated once with g_new0() but never free()'d. Fix the leakage
by adding an attribute to struct PPCE500MachineState which avoids the
allocation.
