From 85206bf95313c33a244d6ea4304b01ade95b8b05 Mon Sep 17 00:00:00 2001 From: Lizhe Date: Sun, 19 Mar 2023 12:19:41 +0800 Subject: s390/vfio-ap: remove redundant driver match function If there is no driver match function, the driver core assumes that each candidate pair (driver, device) matches, see driver_match_device(). Drop the matrix bus's match function that always returned 1 and so implements the same behaviour as when there is no match function Signed-off-by: Lizhe Reviewed-by: Tony Krowiak Link: https://lore.kernel.org/r/20230319041941.259830-1-sensor1010@163.com Signed-off-by: Heiko Carstens Signed-off-by: Vasily Gorbik --- drivers/s390/crypto/vfio_ap_drv.c | 6 ------ 1 file changed, 6 deletions(-) (limited to 'drivers/s390/crypto/vfio_ap_drv.c') diff --git a/drivers/s390/crypto/vfio_ap_drv.c b/drivers/s390/crypto/vfio_ap_drv.c index 997b524bdd2b..9341c000da41 100644 --- a/drivers/s390/crypto/vfio_ap_drv.c +++ b/drivers/s390/crypto/vfio_ap_drv.c @@ -59,14 +59,8 @@ static void vfio_ap_matrix_dev_release(struct device *dev) kfree(matrix_dev); } -static int matrix_bus_match(struct device *dev, struct device_driver *drv) -{ - return 1; -} - static struct bus_type matrix_bus = { .name = "matrix", - .match = &matrix_bus_match, }; static struct device_driver matrix_driver = { -- cgit
