From cc80e3625695ecdfa8a1ac182d7a597aed3edf50 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 24 Jan 2020 15:25:43 +0200 Subject: [PATCH] drm/i915/lvds: use intel_de_*() functions for register access The implicit "dev_priv" local variable use has been a long-standing pain point in the register access macros I915_READ(), I915_WRITE(), POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW(). Replace them with the corresponding new display engine register accessors intel_de_read(), intel_de_write(), intel_de_posting_read(), intel_de_read_fw(), and intel_de_write_fw(). No functional changes.
