HID: potential dereference of null pointer

2021-12-20T10:26:14+00:00

The return value of devm_kzalloc() needs to be checked.
To avoid hdev->dev->driver_data to be null in case of the failure of
alloc.

An overlook from the previous commit: we don't even parse or start the
device, meaning that the device is not presented to user space.

HID: intel-ish-hid: ipc: only enable IRQ wakeup when requested

2021-12-03T08:32:49+00:00

Fixes spurious wakeups from s0ix on Lenovo ThinkPad X1 Cargon Gen 9 on
lid close.

These wakeups are generated by interrupts from the ISH on changes to the
lid status.

By disabling the wake IRQ from the ISH we inhibit these spurious
wakeups while keeping the resume from LID open through the ACPI
interrupt.

Reports on the Lenovo forums indicate that Lenovo ThinkPad X1 Yoga Gen6
is also affected.

HID: add USB_HID dependancy to hid-prodikeys

2021-12-03T08:15:53+00:00

The prodikeys HID driver only controls USB devices, yet did not have a
dependancy on USB_HID.  This causes build errors on some configurations
like nios2 when building due to new changes to the prodikeys driver.

2021-12-02T14:36:18+00:00

When emulating the device through uhid, there is a chance we don't have
output reports and so report_field is null.

HID: sony: fix error path in probe

2021-12-02T14:36:18+00:00

When the setup of the GHL fails, we are not calling hid_hw_stop().
This leads to the hidraw node not being released, meaning a crash
whenever somebody attempts to open the file.

HID: add USB_HID dependancy on some USB HID drivers

2021-12-02T14:36:18+00:00

Some HID drivers are only for USB drivers, yet did not depend on
CONFIG_USB_HID.  This was hidden by the fact that the USB functions were
stubbed out in the past, but now that drivers are checking for USB
devices properly, build errors can occur with some random
configurations.
