2024-06-28Input: rohm_bu21023 - switch to using cleanup functionsDmitry Torokhov1-21/+19
Start using __free() and guard() primitives to simplify the code and error handling. Link: https://lore.kernel.org/r/20240609235134.614592-3-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2024-06-28Input: rohm_bu21023 - switch to using sysfs_emit()Dmitry Torokhov1-3/+3
sysfs_emit() is preferred over snprintf() for sysfs attribute handling. Link: https://lore.kernel.org/r/20240609235134.614592-2-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

The code to toggle axis swapping and inversion is repetitive and can be factored out. Link: https://lore.kernel.org/r/20240609235134.614592-1-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2024-05-13Input: drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König1-1/+1
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.

2023-09-06Input: rohm_bu21023 - use device core to create driver-specific device ↵Dmitry Torokhov1-10/+2
attributes 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.

2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+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.

2022-12-02Input: rohm_bu21023 - Convert to i2c's .probe_new()Uwe Kleine-König1-3/+2
The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted.

2018-07-13input: rohm_bu21023: switch to i2c_lock_bus(..., I2C_LOCK_SEGMENT)Peter Rosin1-2/+2
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.

2017-09-29Input: rohm_bu21023 - use managed devm_device_add_groupAndi Shyti1-16/+1
Commit 57b8ff070f98 ("driver core: add devm_device_add_group() and friends") has added the managed version for creating sysfs group files. Use devm_device_add_group instead of sysfs_create_group and remove the action that cleans the sysfs file when exiting the driver.
