2023-06-08	hwmon: Switch i2c drivers back to use .probe()	Uwe Kleine-König	1	-1/+1
	After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-12-05	hwmon: use simple i2c probe	Stephen Kitt	1	-3/+2
	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@sk2.org> Link: https://lore.kernel.org/r/20221011143309.3141267-1-steve@sk2.org Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2020-12-03	hwmon: (max127) Add Maxim MAX127 hardware monitoring driver	Tao Ren	1	-0/+352
