rtc: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-07-06T22:40:29+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove a comma after the sentinel entry in rtc-hym8563.

rtc: ds3232: avoid unused-const-variable warning

2024-01-08T00:15:49+00:00

Fix the following warning when CONFIG_I2C is not set but CONFIG_SPI_MASTER is set. warning: 'ds3232_pm_ops' defined but not used [-Wunused-const-variable=] 'ds3232_pm_ops' is only used by rtc-ds3232 i2c driver, so move the device PM callbacks inside #if IS_ENABLED(CONFIG_I2C).

rtc: Switch i2c drivers back to use .probe()

2023-06-06T21:29:37+00:00

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.

rtc: use simple i2c probe

2022-06-24T19:24:02+00:00

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 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: Alexandre Belloni Link: https://lore.kernel.org/r/20220610162346.4134094-1-steve@sk2.org

rtc: add devm_ prefix to rtc_nvmem_register()

2020-11-19T11:50:11+00:00

rtc_nvmem_register() is a managed interface. It doesn't require any release function to be called at driver detach. To avoid confusing driver authors, let's rename it to devm_rtc_nvmem_register() and add it to the list of managed interfaces in Documentation/.
