Subjectlinux-next: manual merge of the drm-intel tree with Linus' tree
Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in:

drivers/gpu/drm/i915/intel_runtime_pm.c

between commitis:

bc5f2ab11ca6 ("drm/i915/skl: Don't call intel_prepare_ddi when encoder list isn't yet initialized.")
1b0e3a049efe ("drm/i915/skl: disable display side power well support for now")

from Linus' tree and commit:

f0ab43e6c338 ("drm/i915: Introduce a gmbus power domain")
c2b16152e0b3 ("drm/i915/skl: remove redundant DDI/IRQ reinitialization during PW1 enabling")

from the drm-intel tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
