* Input: drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König2024-05-131-1/+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.

* Input: Switch i2c drivers back to use .probe()Uwe Kleine-König2023-05-171-1/+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.

* Input: rmi4 - switch to SYSTEM_SLEEP/RUNTIME_PM_OPS() and pm_ptr()Jonathan Cameron2023-01-271-8/+3
| | | | | | | | | | | | | | | | | | | | SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() are deprecated as they requires explicit protection against unused function warnings. The new combination of pm_ptr() and SYSTEM_SLEEP_PM_OPS() / RUNTIME_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the #ifdef guards. Whilst all 3 sets of callbacks are similar, there are small differences that make it challenging to use a single pm_dev_ops structure - hence leave the duplication as it stands.

| | | | | | | | | MODULE_VERSION is useless for in-kernel drivers, so just remove all usage of it in the rmi4 drivers. Now that this is gone, the RMI_DRIVER_VERSION macro was also removed as it was pointless.

* Input: synaptics-rmi4 - when registering sensors do not call them "drivers"Dmitry Torokhov2017-04-031-25/+26
| | | | | | | | | | We are not registering drivers, but transport devices (AKA sensors), so let's call them that. Also let's rename "retval" to "error" in probe() functions as the variables are used to store error codes.

* | Input: synaptics-rmi4 - fix error handling in I2C transport driverGuenter Roeck2016-10-041-12/+26
|/ | | | | | | | | | | | Instantiating the rmi4 I2C transport driver without interrupts assigned (for example using manual i2c instantiation from the command line) caused the driver to fail to load, but it does not clean up its regulator or transport device registrations. Result is a crash at a later time, for example when rebooting the system.
