From 6b42f491e17ce13f5ff7f2d1f49c73a0f4c47b20 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 11 Apr 2022 16:14:01 +0200 Subject: vfio/mdev: Remove mdev_parent_ops The last useful member in this struct is the supported_type_groups, move it to the mdev_driver and delete mdev_parent_ops. Replace it with mdev_driver as an argument to mdev_register_device() Signed-off-by: Jason Gunthorpe Signed-off-by: Christoph Hellwig Signed-off-by: Zhi Wang Link: http://patchwork.freedesktop.org/patch/msgid/20220411141403.86980-33-hch@lst.de Reviewed-by: Kirti Wankhede Reviewed-by: Zhi Wang --- drivers/s390/cio/vfio_ccw_ops.c | 7 +------ drivers/s390/crypto/vfio_ap_ops.c | 9 ++------- 2 files changed, 3 insertions(+), 13 deletions(-) (limited to 'drivers/s390') diff --git a/drivers/s390/cio/vfio_ccw_ops.c b/drivers/s390/cio/vfio_ccw_ops.c index d8589afac272..c4d60cdbf247 100644 --- a/drivers/s390/cio/vfio_ccw_ops.c +++ b/drivers/s390/cio/vfio_ccw_ops.c @@ -656,17 +656,12 @@ struct mdev_driver vfio_ccw_mdev_driver = { }, .probe = vfio_ccw_mdev_probe, .remove = vfio_ccw_mdev_remove, -}; - -static const struct mdev_parent_ops vfio_ccw_mdev_ops = { - .owner = THIS_MODULE, - .device_driver = &vfio_ccw_mdev_driver, .supported_type_groups = mdev_type_groups, }; int vfio_ccw_mdev_reg(struct subchannel *sch) { - return mdev_register_device(&sch->dev, &vfio_ccw_mdev_ops); + return mdev_register_device(&sch->dev, &vfio_ccw_mdev_driver); } void vfio_ccw_mdev_unreg(struct subchannel *sch) diff --git a/drivers/s390/crypto/vfio_ap_ops.c b/drivers/s390/crypto/vfio_ap_ops.c index 6e08d04b605d..ee0a3bf8f476 100644 --- a/drivers/s390/crypto/vfio_ap_ops.c +++ b/drivers/s390/crypto/vfio_ap_ops.c @@ -1496,12 +1496,7 @@ static struct mdev_driver vfio_ap_matrix_driver = { }, .probe = vfio_ap_mdev_probe, .remove = vfio_ap_mdev_remove, -}; - -static const struct mdev_parent_ops vfio_ap_matrix_ops = { - .owner = THIS_MODULE, - .device_driver = &vfio_ap_matrix_driver, - .supported_type_groups = vfio_ap_mdev_type_groups, + .supported_type_groups = vfio_ap_mdev_type_groups, }; int vfio_ap_mdev_register(void) @@ -1514,7 +1509,7 @@ int vfio_ap_mdev_register(void) if (ret) return ret; - ret = mdev_register_device(&matrix_dev->device, &vfio_ap_matrix_ops); + ret = mdev_register_device(&matrix_dev->device, &vfio_ap_matrix_driver); if (ret) goto err_driver; return 0; -- cgit v1.2.3
