A number of driver lock-ups have been reported on a few systems over the past few years, all related to interrupt mode. So let's make it more tolerant to unreliable hardware or whatever the actual problem is. i2c-i801: Use wait_event_timeout to wait for interrupts i2c-i801: Fallback to polling if request_irq() fails i2c-i801: Check if interrupts are disabled i2c-i801: Drop useless debug message Changes since v1: * Updated according to Wolfram's review. Thanks! -- Jean Delvare SUSE L3 Support
