Subject: [PATCH v2 4/9] drm/nouveau: tegra: Do not try to disable PCI device
Date: Sat,  2 Nov 2019 18:56:32 +0100	[thread overview]
Message-ID: <20191102175637.3065-5-thierry.reding@gmail.com> (raw)
In-Reply-To: <20191102175637.3065-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

When Nouveau is instantiated on top of a platform device, the dev->pdev
field will be NULL and calling pci_disable_device() will crash. Move the
PCI disabling code to the PCI specific driver removal code.
