Subject: [PULL 2/5] hw/ide/sii3112: Use qdev gpio rather than qemu_allocate_irqs()
Date: Fri, 27 Mar 2020 16:14:58 -0400	[thread overview]
Message-ID: <20200327201501.1417-3-jsnow@redhat.com> (raw)
In-Reply-To: <20200327201501.1417-1-jsnow@redhat.com>

From: Peter Maydell <peter.maydell@linaro.org>

Coverity points out (CID 1421984) that we are leaking the
memory returned by qemu_allocate_irqs(). We can avoid this
leak by switching to using qdev_init_gpio_in(); the base
class finalize will free the irqs that this allocates under
the hood.
