From 683bb2424cd5be17cca02067b038e9da5aa68dc6 Mon Sep 17 00:00:00 2001 From: Iker Pedrosa Date: Sat, 20 Sep 2025 11:45:42 +0200 Subject: [PATCH] drm/solomon: Use drm_WARN_ON_ONCE instead of WARN_ON To prevent log spam, convert all instances to the DRM-specific drm_WARN_ON_ONCE() macro. This ensures that a warning is emitted only the first time the condition is met for a given device instance, which is the desired behavior within the graphics subsystem.
