From 81987bd58b558be71dc4d8adf163f8c787a1c3e9 Mon Sep 17 00:00:00 2001 From: Zhenzhong Duan Date: Tue, 7 May 2024 14:42:42 +0800 Subject: [PATCH] vfio/pci: Use g_autofree in vfio_realize MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Local pointer name is allocated before vfio_attach_device() call and freed after the call. Same for tmp when calling realpath(). Use 'g_autofree' to avoid the g_free() calls.
