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.

2023-01-28Input: rmi4 - switch to SYSTEM_SLEEP/RUNTIME_PM_OPS() and pm_ptr()Jonathan Cameron1-8/+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.

2022-12-03Input: rmi_i2c - 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.

2018-01-17Input: synaptics_rmi4 - remove unneeded MODULE_VERSION() usageGreg Kroah-Hartman1-1/+0
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.

2017-04-04Input: synaptics-rmi4 - when registering sensors do not call them "drivers"Dmitry Torokhov1-25/+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.

2016-11-09Input: synaptics-rmi4 - move IRQ handling to rmi_driverBjorn Andersson1-69/+5
The attn IRQ is related to the chip, rather than the transport, so move all handling of interrupts to the core driver. This also makes sure that there are no races between interrupts and availability of the resources used by the core driver.

2016-10-04Input: synaptics-rmi4 - fix error handling in I2C transport driverGuenter Roeck1-12/+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.
