[PATCH] drm/amdgpu: Inline drm_simple_encoder_init()

From: Nicolás Antinori

Date: Wed Jul 08 2026 - 18:21:21 EST


Simple KMS helpers are deprecated because they introduce an unnecessary
intermediate layer between atomic modesetting and the DRM driver.

Inline the functionality of drm_simple_encoder_init() to remove
dependencies on these deprecated helpers.
