Subject: [PATCH] arch: Fix name collision with ACPI's video.o
Date: Fri, 17 May 2024 11:14:33 +0200 [thread overview]
Message-ID: <20240517091557.25800-1-tzimmermann@suse.de> (raw)
Commit 2fd001cd3600 ("arch: Rename fbdev header and source files")
renames the video source files under arch/ such that they do not
refer to fbdev any longer. The new files named video.o conflict with
ACPI's video.ko module. Modprobing the ACPI module can then fail with
warnings about missing symbols, as shown below.
(i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_unregister (err -2)
(i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_register_backlight (err -2)
(i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol __acpi_video_get_backlight_type (err -2)
(i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_register (err -2)
Fix the issue by renaming the architecture's video.o to video-common.o.
