Avoid resetting the module-wide i8042_platform_device pointer in i8042_probe() or i8042_remove(), so that the device can be properly destroyed by i8042_exit() on module unload. Fixes: 9222ba68 ("Input: i8042 - add deferred probe support") Signed-off-by:

Like on the Acer Switch 10 SW5-012, the Acer Switch V 10 SW5-017's _LID method messes with home- and power-button GPIO IRQ settings, causing an IRQ storm. Add a quirk entry for the Acer Switch V 10 to the dmi_use_low_level_irq[] DMI quirk list, to use low-level IRQs on this model, fixing the IRQ storm. Signed-off-by:

It seems that the Windows drivers for the ACPI0011 soc_button_array device use low level triggered IRQs rather then using edge triggering. Some ACPI tables depend on this, directly poking the GPIO controller's registers to clear the trigger type when closing a laptop's/2-in-1's lid and re-instating the trigger when opening the lid again. Linux sets the edge/level on which to trigger to both low+high since it is using edge type IRQs, the ACPI tables then ends up also setting the bit for level IRQs and since both low and high level have been selected by Linux we get an IRQ storm leading to soft lockups. As a workaround for this the soc_button_array already contains a DMI quirk table with device models known to have this issue. Add a module parameter for this so that users can easily test if their device is affected too and so that they can use the module parameter as a workaround. Signed-off-by:

syzbot is reporting uninitialized value at iforce_init_device() [1], for commit 6ac0aec6 ("Input: iforce - allow callers supply data buffer when fetching device IDs") is checking that valid length is shorter than bytes to read. Since iforce_get_id_packet() stores valid length when returning 0, the caller needs to check that valid length is longer than or equals to bytes to read. Reported-by:

On ACPI systems (irq_pin_access_method == IRQ_PIN_ACCESS_ACPI_*) the driver does not reset the controller at probe time, because sometimes the system firmware loads a config and resetting might loose this config. On the Nanote UMPC-01 device OTOH the config is in flash of the controller, the controller needs a reset to load this; and the system firmware does not reset the controller on a cold boot. To fix the Nanote UMPC-01 touchscreen not working on a cold boot, try resetting the controller and then re-reading the config when encountering a config with 0 width/height/max_touch_num value and the controller has not already been reset by goodix_ts_probe(). This should be safe to do in general because normally we should never encounter a config with 0 width/height/max_touch_num. Doing this in general not only avoids the need for a DMI quirk, but also might help other systems. Signed-off-by:
