[Intel-gfx] [PATCH 1/5] drm/i915/ipc: refactor and rename IPC functions
Jani Nikula

Mon Sep 12 11:45:12 UTC 2022
Rename the IPC functions to have skl_watermark_ipc_ prefix, rename
enable to update to reflect what the function actually does, and add
enabled function to abstract direct ->ipc_enabled access for state
query.
