HID: i2c-hid: Add support for ACPI GPIO interrupts
The HID over I2C specification allows to have the interrupt for a HID device to be GPIO instead of directly connected to the IO-APIC. Add support for this so that when the driver does not find proper interrupt number from the I2C client structure we check if it has ACPI GpioInt() resource listed in _CRS. If it is found we convert it to an interrupt number and use it instead. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
