Subject: [PATCH] Input: tnetv107x-keypad - make irqs signed for error handling
There is a bug in keypad_probe() where we do:
kp->irq_press = platform_get_irq_byname(pdev, "press");
kp->irq_release = platform_get_irq_byname(pdev, "release");
if (kp->irq_press < 0 || kp->irq_release < 0) {
The problem is that these irq variables are unsigned so the error
handling doesn't work. I've changed them to signed values.
