Subject: [PATCH v2 02/11] vfio/pci: Use g_autofree in iommufd_cdev_get_info_iova_range()
Date: Tue,  7 May 2024 14:42:43 +0800	[thread overview]
Message-ID: <20240507064252.457884-3-zhenzhong.duan@intel.com> (raw)
In-Reply-To: <20240507064252.457884-1-zhenzhong.duan@intel.com>

Local pointer info is freed before return from
iommufd_cdev_get_info_iova_range().

Use 'g_autofree' to avoid the g_free() calls.
