From 0d9030a2c3214cf8f9bfff84204e0f5ba5e790d7 Mon Sep 17 00:00:00 2001 From: Octavian Purdila Date: Fri, 5 Jun 2015 16:59:43 +0300 Subject: [PATCH] rtc: fix drivers that consider 0 as a valid IRQ in client->irq Since dab472eb931b ("i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned"), 0 is not a valid i2c client irq anymore, so change all driver's checks accordingly. The same issue occurs when the device is instantiated via device tree with no IRQ, or from the i2c sysfs interface, even before the patch above.
