drm/appletbdrm: Use kvzalloc for big allocations

2026-04-27T09:33:01+00:00

This driver is attached to a ~2000x80 screen, which is a lot more than a single page. This causes out of memory errors in some rare cases.

drm/arcpgu: fix device node leak

2026-04-14T09:21:48+00:00

This function gets a device_node reference via of_graph_get_remote_port_parent() and stores it in encoder_node, but never puts that reference. Add it. There used to be a of_node_put(encoder_node) but it has been removed by mistake during a rework in commit 3ea66a794fdc ("drm/arc: Inline arcpgu_drm_hdmi_init").

drm/panel-mipi-dbi: Use regular atomic helpers; drop simple-display helpers

2026-03-25T14:05:02+00:00

Replace simple-display helpers with regular atomic helpers. Store the pipeline elements in struct panel_mipi_dbi_device and initialize them as part of probing the device. Use mipi-dbi's existing helpers and initializer macros where possible. Effectively open-codes the modesetting code in the initializer helpers of mipi-dbi and simple-display. Panel-mipi-dbi requires a custom helper for CRTC enablement, and non-freeing cleanup of the pipeline. v2: - fix connector initialization Signed-off-by: Thomas Zimmermann Acked-by: David Lechner Tested-by: David Lechner Reviewed-by: Dmitry Baryshkov Link: https://patch.msgid.link/20260319160110.109610-11-tzimmermann@suse.de
