From 1b82111faebc24427c76b83738566bda7f315225 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Thu, 28 Jan 2016 12:30:06 +0900 Subject: [PATCH] drm/nouveau/device/tegra: fix uninitialized IRQ number nvkm_device_tegra_new initializes the irq member of the Tegra device to -1 in order to signal that it is uninitialized. However, nvkm_device_tegra_fini tests it against 0 to check whether an IRQ has been allocated or not. This leads to free_irq being called on -1 during device initialization. Fix this by using 0 as the uninitialized value everywhere.
