Input: soc_button_array - add usage-page 0x01 usage-id 0xca mapping
The ACPI0011 _DSD button descriptor on a CHT based Intel Compute Sticks contains a mapping for usage-page 0x01 usage-id 0xca. As described in hutrr52_system_display_rotation_lock_controls_0.pdf this should be mapped as a "System Display Rotation Lock Slider Switch", this commit adds support for this, silencing the following warning: soc_button_array ACPI0011:00: Unknown button index 4 upage 01 usage ca, ignoring Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
