YueHaibing c2530cc961 drm/bridge: tpd12s015: Fix irq registering in tpd12s015_probe ... gpiod_to_irq() return negative value in case of error, the existing code doesn't handle negative error codes. If the HPD gpio supports IRQs (gpiod_to_irq returns a valid number), we use the IRQ. If it doesn't (gpiod_to_irq returns an error), it gets polled via detect().
