similar to: [PATCH] drm/nouveau: Use dev_get_drvdata where possible

Instead of using to_pci_dev + pci_get_drvdata, use dev_get_drvdata to make code simpler.

drm_put_dev also calls drm_dev_unregister, so dev will be unregistered twice. Replace it with drm_dev_put to fix it.

Since this is so confusing, we actually have a todo to remove drm_put_dev completely from the codebase

Now that we have ->pre_transfer() and ->post_transfer() for DP AUX channel devices, we can implement these hooks in order to ensure that the GPU is actually woken up before AUX transactions happen. This fixes /dev/drm_dp_aux* not working while the GPU is suspended, along with some more rare issues where the GPU might runtime-suspend if the time between two DP AUX channel transactions ends up

why the nouveau_is_rpm_worker stuff?

This should make systems more stable where resuming the GPU fails. This can happen due to bad firmware or due to a bug within the kernel. The last thing which should happen in either case is an unusable system. v2: do the same in nouveau_pmops_resume Tested-by: Karl Hastings <kazen at redhat.com> Signed-off-by: Karol Herbst <kherbst at redhat.com> --- drm/nouveau/nouveau_drm.c | 31

We need to call drm_helper_hpd_irq_event() on resume to properly detect monitor connection / disconnection on some laptops, use hpd_work for this to avoid deadlocks.

On a failed resume we may experience unrecoverable errors. Plumb the error code through to actually let the driver fail. On a reverse-prime setup this helps the drm subsystem to at least recover the integrated gpu. This can especially happen with secboot timing out, leaving the hardware in a non-functioning state.
