Som of the platforms may connect the INT pin via inversion logic effectively make the triggering to be active-low. Remove explicit trigger flag to respect the settings from firmware. Without this change even idling chip produces spurious interrupts and kernel disables the line in the result: irq 33: nobody cared (try booting with the "irqpoll" option) CPU: 0 UID: 0 PID: 125 Comm: irq/33-i2c-INT3 Not tainted 6.12.0-00236-g8b874ed11dae #64 Hardware name: Intel Corp.
