External email: Use caution opening links or attachments I noticed on Nexus 7 that after rebooting from downstream kernel to upstream, the GPIO interrupt is triggering non-stop despite interrupts being disabled for all of GPIOs. This happens because Nexus 7 uses a soft-reboot, meaning that bootloader should take care of resetting hardware, but the bootloader doesn't do it well. As a result, GPIO interrupt may be left ON at a boot time. Let's mask all GPIO interrupts at the driver's initialization time in order to resolve the issue.
