Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19Z

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 commas after the sentinel entries.

Input: rohm_bu21023 - use device core to create driver-specific device attributes

2023-09-06T21:29:03Z

Instead of creating driver-specific device attributes with devm_device_add_group() have device core do this by setting up dev_groups pointer in the driver structure.

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

2023-05-17T16:59:11Z

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.

Input: rohm_bu21023 - Convert to i2c's .probe_new()

2022-12-02T22:53:46Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-256-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

input: rohm_bu21023: switch to i2c_lock_bus(..., I2C_LOCK_SEGMENT)

2018-07-12T22:08:14Z

Locking the root adapter for __i2c_transfer will deadlock if the device sits behind a mux-locked I2C mux. Switch to the finer-grained i2c_lock_bus with the I2C_LOCK_SEGMENT flag. If the device does not sit behind a mux-locked mux, the two locking variants are equivalent. Signed-off-by: Peter Rosin Acked-by: Dmitry Torokhov Signed-off-by: Wolfram Sang
