From e99a3dec3a7ac903c20b6843693d53087fb7bcab Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Fri, 3 Feb 2017 14:47:02 -0800 Subject: gpu: nvgpu: Disable IRQs only if enabled In the PCI init/de-init code only disable IRQs if they were enabled. The enable happens in the common power_on code. The PCI routines could both be called without the common power_on code being called which causes an extra disable to happen.
