Subject: [Intel-gfx] [PATCH 2/2] drm/i915/display: use intel_de_*() functions for register access
Date: Fri, 14 Feb 2020 16:09:10 +0200 [thread overview]
Message-ID: <20200214140910.23194-2-jani.nikula@intel.com> (raw)
In-Reply-To: <20200214140910.23194-1-jani.nikula@intel.com>
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.
Generated using the following semantic patch:
