From baf34f3bbe6de7ac1efb4e31342403e9cca8888d Mon Sep 17 00:00:00 2001 From: Stephen Kitt Date: Wed, 12 Oct 2022 18:33:00 +0200 Subject: HID: i2c: use simple i2c probe All these drivers have an i2c probe function which doesn't use the "struct i2c_device_id *id" parameter, so they can trivially be converted to the "probe_new" style of probe with a single argument. This is part of an ongoing transition to single-argument i2c probe functions. Old-style probe functions involve a call to i2c_match_id: in drivers/i2c/i2c-core-base.c, /* * When there are no more users of probe(), * rename probe_new to probe. */ if (driver->probe_new) status = driver->probe_new(client); else if (driver->probe) status = driver->probe(client, i2c_match_id(driver->id_table, client)); else status = -EINVAL; Drivers which don't need the second parameter can be declared using probe_new instead, avoiding the call to i2c_match_id. Drivers which do can still be converted to probe_new-style, calling i2c_match_id themselves (as is done currently for of_match_id). This change was done using the following Coccinelle script, and fixed up for whitespace changes: @ rule1 @ identifier fn; identifier client, id; @@ - static int fn(struct i2c_client *client, const struct i2c_device_id *id) + static int fn(struct i2c_client *client) { ...when != id } @ rule2 depends on rule1 @ identifier rule1.fn; identifier driver; @@ struct i2c_driver driver = { - .probe + .probe_new = ( fn | - &fn + fn ) , }; Signed-off-by: Stephen Kitt Signed-off-by: Jiri Kosina --- drivers/hid/i2c-hid/i2c-hid-of-elan.c | 5 ++--- drivers/hid/i2c-hid/i2c-hid-of-goodix.c | 5 ++--- drivers/hid/i2c-hid/i2c-hid-of.c | 5 ++--- 3 files changed, 6 insertions(+), 9 deletions(-) (limited to 'drivers/hid') diff --git a/drivers/hid/i2c-hid/i2c-hid-of-elan.c b/drivers/hid/i2c-hid/i2c-hid-of-elan.c index 2d991325e734..76ddc8be1cbb 100644 --- a/drivers/hid/i2c-hid/i2c-hid-of-elan.c +++ b/drivers/hid/i2c-hid/i2c-hid-of-elan.c @@ -68,8 +68,7 @@ static void elan_i2c_hid_power_down(struct i2chid_ops *ops) regulator_disable(ihid_elan->vcc33); } -static int i2c_hid_of_elan_probe(struct i2c_client *client, - const struct i2c_device_id *id) +static int i2c_hid_of_elan_probe(struct i2c_client *client) { struct i2c_hid_of_elan *ihid_elan; @@ -119,7 +118,7 @@ static struct i2c_driver elan_i2c_hid_ts_driver = { .probe_type = PROBE_PREFER_ASYNCHRONOUS, .of_match_table = of_match_ptr(elan_i2c_hid_of_match), }, - .probe = i2c_hid_of_elan_probe, + .probe_new = i2c_hid_of_elan_probe, .remove = i2c_hid_core_remove, .shutdown = i2c_hid_core_shutdown, }; diff --git a/drivers/hid/i2c-hid/i2c-hid-of-goodix.c b/drivers/hid/i2c-hid/i2c-hid-of-goodix.c index ec6c73f75ffe..29c6cb174032 100644 --- a/drivers/hid/i2c-hid/i2c-hid-of-goodix.c +++ b/drivers/hid/i2c-hid/i2c-hid-of-goodix.c @@ -87,8 +87,7 @@ static int ihid_goodix_vdd_notify(struct notifier_block *nb, return ret; } -static int i2c_hid_of_goodix_probe(struct i2c_client *client, - const struct i2c_device_id *id) +static int i2c_hid_of_goodix_probe(struct i2c_client *client) { struct i2c_hid_of_goodix *ihid_goodix; int ret; @@ -167,7 +166,7 @@ static struct i2c_driver goodix_i2c_hid_ts_driver = { .probe_type = PROBE_PREFER_ASYNCHRONOUS, .of_match_table = of_match_ptr(goodix_i2c_hid_of_match), }, - .probe = i2c_hid_of_goodix_probe, + .probe_new = i2c_hid_of_goodix_probe, .remove = i2c_hid_core_remove, .shutdown = i2c_hid_core_shutdown, }; diff --git a/drivers/hid/i2c-hid/i2c-hid-of.c b/drivers/hid/i2c-hid/i2c-hid-of.c index 97a27a803f58..10176568133a 100644 --- a/drivers/hid/i2c-hid/i2c-hid-of.c +++ b/drivers/hid/i2c-hid/i2c-hid-of.c @@ -66,8 +66,7 @@ static void i2c_hid_of_power_down(struct i2chid_ops *ops) ihid_of->supplies); } -static int i2c_hid_of_probe(struct i2c_client *client, - const struct i2c_device_id *dev_id) +static int i2c_hid_of_probe(struct i2c_client *client) { struct device *dev = &client->dev; struct i2c_hid_of *ihid_of; @@ -138,7 +137,7 @@ static struct i2c_driver i2c_hid_of_driver = { .of_match_table = of_match_ptr(i2c_hid_of_match), }, - .probe = i2c_hid_of_probe, + .probe_new = i2c_hid_of_probe, .remove = i2c_hid_core_remove, .shutdown = i2c_hid_core_shutdown, .id_table = i2c_hid_of_id_table, -- cgit v1.2.3
