Date: Sun, 19 Mar 2023 12:41:07 +0800 From: Lizhe <sensor1010@....com> To: zbr@...emap.net Cc: linux-kernel@...r.kernel.org, Lizhe <sensor1010@....com> Subject: [PATCH v1] w1/w1.c : Remove 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 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 <sensor1010@....com> --- drivers/w1/w1.c | 6 ------ 1 file changed, 6 deletions(-) diff --git a/drivers/w1/w1.c b/drivers/w1/w1.c index 9d199fed9628..e7e42f9dabf4 100644 --- a/drivers/w1/w1.c +++ b/drivers/w1/w1.c @@ -58,11 +58,6 @@ MODULE_PARM_DESC(slave_ttl, DEFINE_MUTEX(w1_mlock); LIST_HEAD(w1_masters); -static int w1_master_match(struct device *dev, struct device_driver *drv) -{ - return 1; -} - static int w1_master_probe(struct device *dev) { return -ENODEV; @@ -174,7 +169,6 @@ static int w1_uevent(const struct device *dev, struct kobj_uevent_env *env); static struct bus_type w1_bus_type = { .name = "w1", - .match = w1_master_match, .uevent = w1_uevent, }; -- 2.34.1
