From f0f195d1a3aedef126c3ed159712ed57a34daa1c Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Tue, 24 Sep 2024 09:12:47 +0200 Subject: drm/fbdev-shmem: Support struct drm_driver.fbdev_probe Rework fbdev probing to support fbdev_probe in struct drm_driver and reimplement the old fb_probe callback on top of it. Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. This change allows the common fbdev client to run on top of SHMEM- based DRM drivers.
