[PATCH 12/21] drm/nouveau/nvkm: prepare pci/tegra probe()/remove() functions

Thu Jun 13 17:00:04 UTC 2024
Rename, and modify the signatures of nvkm_device_{pci,tegra}_new() to be
consistent with pci/platform driver probe() functions.
The DRM driver is still calling the functions as it did before, just via
the new pci/platform driver structs in NVKM that will eventually be used
for driver registration.
