gpu: host1x: Fix compile error when IOMMU API is not available
In case the IOMMU API is not available compiling host1x fails with the following error: In file included from drivers/gpu/host1x/hw/host1x06.c:27: drivers/gpu/host1x/hw/channel_hw.c: In function ‘host1x_channel_set_streamid’: drivers/gpu/host1x/hw/channel_hw.c:118:30: error: implicit declaration of function ‘dev_iommu_fwspec_get’; did you mean ‘iommu_fwspec_free’? [-Werror=implicit-function-declaration] struct iommu_fwspec *spec = dev_iommu_fwspec_get(channel->dev->parent); ^~~~~~~~~~~~~~~~~~~~ iommu_fwspec_free Fixes: de5469c21ff9 ("gpu: host1x: Program the channel stream ID") Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Thierry Reding <treding@nvidia.com>
