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 --- samples/vfio-mdev/mbochs.c | 9 ++------- samples/vfio-mdev/mdpy.c | 9 ++------- samples/vfio-mdev/mtty.c | 9 ++------- 3 files changed, 6 insertions(+), 21 deletions(-) (limited to 'samples') diff --git a/samples/vfio-mdev/mbochs.c b/samples/vfio-mdev/mbochs.c index e90c8552cc31..344c2901a82b 100644 --- a/samples/vfio-mdev/mbochs.c +++ b/samples/vfio-mdev/mbochs.c @@ -1412,12 +1412,7 @@ static struct mdev_driver mbochs_driver = { }, .probe = mbochs_probe, .remove = mbochs_remove, -}; - -static const struct mdev_parent_ops mdev_fops = { - .owner = THIS_MODULE, - .device_driver = &mbochs_driver, - .supported_type_groups = mdev_type_groups, + .supported_type_groups = mdev_type_groups, }; static const struct file_operations vd_fops = { @@ -1462,7 +1457,7 @@ static int __init mbochs_dev_init(void) if (ret) goto err_class; - ret = mdev_register_device(&mbochs_dev, &mdev_fops); + ret = mdev_register_device(&mbochs_dev, &mbochs_driver); if (ret) goto err_device; diff --git a/samples/vfio-mdev/mdpy.c b/samples/vfio-mdev/mdpy.c index fe5d43e797b6..e8c46eb2e246 100644 --- a/samples/vfio-mdev/mdpy.c +++ b/samples/vfio-mdev/mdpy.c @@ -723,12 +723,7 @@ static struct mdev_driver mdpy_driver = { }, .probe = mdpy_probe, .remove = mdpy_remove, -}; - -static const struct mdev_parent_ops mdev_fops = { - .owner = THIS_MODULE, - .device_driver = &mdpy_driver, - .supported_type_groups = mdev_type_groups, + .supported_type_groups = mdev_type_groups, }; static const struct file_operations vd_fops = { @@ -771,7 +766,7 @@ static int __init mdpy_dev_init(void) if (ret) goto err_class; - ret = mdev_register_device(&mdpy_dev, &mdev_fops); + ret = mdev_register_device(&mdpy_dev, &mdpy_driver); if (ret) goto err_device; diff --git a/samples/vfio-mdev/mtty.c b/samples/vfio-mdev/mtty.c index 4f227dc26785..f42a59ed2e3f 100644 --- a/samples/vfio-mdev/mtty.c +++ b/samples/vfio-mdev/mtty.c @@ -1301,12 +1301,7 @@ static struct mdev_driver mtty_driver = { }, .probe = mtty_probe, .remove = mtty_remove, -}; - -static const struct mdev_parent_ops mdev_fops = { - .owner = THIS_MODULE, - .device_driver = &mtty_driver, - .supported_type_groups = mdev_type_groups, + .supported_type_groups = mdev_type_groups, }; static void mtty_device_release(struct device *dev) @@ -1357,7 +1352,7 @@ static int __init mtty_dev_init(void) if (ret) goto err_class; - ret = mdev_register_device(&mtty_dev.dev, &mdev_fops); + ret = mdev_register_device(&mtty_dev.dev, &mtty_driver); if (ret) goto err_device; return 0; -- cgit v1.2.3-58-ga151
