[Intel-gfx] [PATCH v3 4/8] drm/i915: move and rename i915_runtime_pm
Daniele Ceraolo Spurio
daniele.ceraolospurio at intel.com
Thu Jun 13 23:21:52 UTC 2019
Asserts aside, all the code working on this structure is in
intel_runtime_pm.c and uses the intel_ prefix, so move the
structure to intel_runtime_pm.h and adopt the same prefix.
Since all the asserts are now working on the runtime_pm structure,
bring them across as well.
v2: drop unneeded include (Chris), don't rename debugfs, rebase
