[PATCH xf86-video-amdgpu 07/19] Factor out common code to amdgpu_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Emil Velikov <emil.velikov@xxxxxxxxxxxxx>

Keep the distinct pci/platform screen management in the separate probe
entry point and fold the rest into a single function.
