Subject: [PATCH v2 01/23] hw/ppc/e500: Do not leak struct boot_info
Date: Sat,  5 Oct 2024 21:45:41 +0200	[thread overview]
Message-ID: <20241005194603.23139-2-shentey@gmail.com> (raw)
In-Reply-To: <20241005194603.23139-1-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.

While at it remove the obsolete /*< private >*/ markers.
