Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()

2023-10-29T02:54:52Z

The put_device() calls rmi_release_function() which frees "fn" so the dereference on the next line "fn->num_of_irqs" is a use after free. Move the put_device() to the end to fix this.

Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport

2023-10-14T00:59:19Z

Touch controllers need some time after receiving reset command for the firmware to finish re-initializing and be ready to respond to commands from the host. The driver already had handling for the post-reset delay for I2C and SPI transports, this change adds the handling to SMBus-connected devices. SMBus devices are peculiar because they implement legacy PS/2 compatibility mode, so reset is actually issued by psmouse driver on the associated serio port, after which the control is passed to the RMI4 driver with SMBus companion device. Note that originally the delay was added to psmouse driver in 92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus mode"), but that resulted in an unwanted delay in "fast" reconnect handler for the serio port, so it was decided to revert the patch and have the delay being handled in the RMI4 driver, similar to the other transports.

Input: synaptics-rmi4 - replace deprecated strncpy

2023-09-30T16:24:15Z

`strncpy` is deprecated for use on NUL-terminated destination strings [1] Let's use memcpy() as the bounds have already been checked and this decays into a simple byte copy from one buffer to another removing any ambiguity that strncpy has.

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: synaptics-rmi4 - fix SPI device ID

2023-02-04T00:53:40Z

Currently, the ID being set to "rmi4_spi" causes this warning: "SPI driver rmi4_spi has no spi_device_id for syna,rmi4-spi" Change the ID to rmi4-spi to stop this warning.

Input: rmi4 - switch to SYSTEM_SLEEP/RUNTIME_PM_OPS() and pm_ptr()

2023-01-27T22:49:52Z

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.
