Tsirkin" <mst@redhat.com>, qemu-devel@nongnu.org Subject: [PATCH] qemu_fw_cfg: use default_groups in kobj_type Date: Wed, 5 Jan 2022 19:31:33 +0100 [thread overview] Message-ID: <20220105183133.2812848-1-gregkh@linuxfoundation.org> (raw) There are currently 2 ways to create a set of sysfs files for a kobj_type, through the default_attrs field, and the default_groups field. Move the firmware qemu_fw_cfg sysfs code to use default_groups field which has been the preferred way since aa30f47cf666 ("kobject: Add support for default attribute groups to kobj_type") so that we can soon get rid of the obsolete default_attrs field.
