Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43Z

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds

drm/meson: Allow build with COMPILE_TEST=y

2024-10-25T07:25:10Z

Allow meson to be built with COMPILE_TEST=y for greater coverage. Builds fine on x86/x86_64 at least.

drm/meson: Use video aperture helpers

DRM's aperture functions have long been implemented as helpers under drivers/video/ for use with fbdev. Avoid the DRM wrappers by calling the video functions directly.

drm/meson: Run DRM default client setup

2024-09-26T06:28:06Z

Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The meson driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann Cc: Neil Armstrong Cc: Kevin Hilman Cc: Jerome Brunet Cc: Martin Blumenstingl Reviewed-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-28-tzimmermann@suse.de

drm_bridge_connector is a "leaf" driver, belonging to the display helper, rather than the "CRTC" drm_kms_helper module. Move the driver to the drm/display and add necessary Kconfig selection clauses.
