Message-Id: <20221012175506.3938001-1-steve@sk2.org> Date: Wed, 12 Oct 2022 19:55:06 +0200 From: Stephen Kitt <steve@....org> To: Andrew Lunn <andrew@...n.ch>, Vivien Didelot <vivien.didelot@...il.com>, Florian Fainelli <f.fainelli@...il.com>, Vladimir Oltean <olteanv@...il.com>, Woojung Huh <woojung.huh@...rochip.com>, UNGLinuxDriver@...rochip.com, George McCollister <george.mccollister@...il.com> Cc: Stephen Kitt <steve@....org>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com>, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] drivers/net/dsa: 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 <steve@....org> --- drivers/net/dsa/lan9303_i2c.c | 5 ++--- drivers/net/dsa/microchip/ksz9477_i2c.c | 5 ++--- drivers/net/dsa/xrs700x/xrs700x_i2c.c | 5 ++--- 3 files changed, 6 insertions(+), 9 deletions(-) diff --git a/drivers/net/dsa/lan9303_i2c.c b/drivers/net/dsa/lan9303_i2c.c index 7d746cd9ca1b..1cb41c36bd47 100644 --- a/drivers/net/dsa/lan9303_i2c.c +++ b/drivers/net/dsa/lan9303_i2c.c @@ -29,8 +29,7 @@ static const struct regmap_config lan9303_i2c_regmap_config = { .cache_type = REGCACHE_NONE, }; -static int lan9303_i2c_probe(struct i2c_client *client, - const struct i2c_device_id *id) +static int lan9303_i2c_probe(struct i2c_client *client) { struct lan9303_i2c *sw_dev; int ret; @@ -106,7 +105,7 @@ static struct i2c_driver lan9303_i2c_driver = { .name = "LAN9303_I2C", .of_match_table = of_match_ptr(lan9303_i2c_of_match), }, - .probe = lan9303_i2c_probe, + .probe_new = lan9303_i2c_probe, .remove = lan9303_i2c_remove, .shutdown = lan9303_i2c_shutdown, .id_table = lan9303_i2c_id, diff --git a/drivers/net/dsa/microchip/ksz9477_i2c.c b/drivers/net/dsa/microchip/ksz9477_i2c.c index 3763930dc6fc..d4f4ceb11e86 100644 --- a/drivers/net/dsa/microchip/ksz9477_i2c.c +++ b/drivers/net/dsa/microchip/ksz9477_i2c.c @@ -14,8 +14,7 @@ KSZ_REGMAP_TABLE(ksz9477, not_used, 16, 0, 0); -static int ksz9477_i2c_probe(struct i2c_client *i2c, - const struct i2c_device_id *i2c_id) +static int ksz9477_i2c_probe(struct i2c_client *i2c) { struct regmap_config rc; struct ksz_device *dev; @@ -120,7 +119,7 @@ static struct i2c_driver ksz9477_i2c_driver = { .name = "ksz9477-switch", .of_match_table = of_match_ptr(ksz9477_dt_ids), }, - .probe = ksz9477_i2c_probe, + .probe_new = ksz9477_i2c_probe, .remove = ksz9477_i2c_remove, .shutdown = ksz9477_i2c_shutdown, .id_table = ksz9477_i2c_id, diff --git a/drivers/net/dsa/xrs700x/xrs700x_i2c.c b/drivers/net/dsa/xrs700x/xrs700x_i2c.c index 54065cdedd35..14ff6887a225 100644 --- a/drivers/net/dsa/xrs700x/xrs700x_i2c.c +++ b/drivers/net/dsa/xrs700x/xrs700x_i2c.c @@ -76,8 +76,7 @@ static const struct regmap_config xrs700x_i2c_regmap_config = { .val_format_endian = REGMAP_ENDIAN_BIG }; -static int xrs700x_i2c_probe(struct i2c_client *i2c, - const struct i2c_device_id *i2c_id) +static int xrs700x_i2c_probe(struct i2c_client *i2c) { struct xrs700x *priv; int ret; @@ -148,7 +147,7 @@ static struct i2c_driver xrs700x_i2c_driver = { .name = "xrs700x-i2c", .of_match_table = of_match_ptr(xrs700x_i2c_dt_ids), }, - .probe = xrs700x_i2c_probe, + .probe_new = xrs700x_i2c_probe, .remove = xrs700x_i2c_remove, .shutdown = xrs700x_i2c_shutdown, .id_table = xrs700x_i2c_id, base-commit: 833477fce7a14d43ae4c07f8ddc32fa5119471a2 -- 2.30.2
