Subject: [Qemu-devel] [PATCH 02/14] hw/misc/bcm2835_property: Add FIXME comment for uninitialized memory
Date: Wed,  4 Sep 2019 19:13:03 +0200	[thread overview]
Message-ID: <20190904171315.8354-3-f4bug@amsat.org> (raw)
In-Reply-To: <20190904171315.8354-1-f4bug@amsat.org>

We are returning unintialized memory, this is probably unsafe.

Reported-by: Peter Maydell <peter.maydell@linaro.org>
