For clang, -Wextra in drivers/gpu/drm/Makefile turns it back but GCC respects turning it off earlier in the command line. Of all the duplicate fields in the initializer, only nfl_bpg_offset is a different value. Clear up the duplicate initializers, keeping the 'false' value for .vbr_enable, as it is bool, and the second value for .nfl_bpg_offset, assuming it is the correct one since it was the one tested in the original change.

2026-01-13drm/panel: simple: restore connector_type fallbackLudovic Desroches
The switch from devm_kzalloc() + drm_panel_init() to devm_drm_panel_alloc() introduced a regression. Several panel descriptors do not set connector_type. For those panels, panel_simple_probe() used to compute a connector type (currently DPI as a fallback) and pass that value to drm_panel_init(). After the conversion to devm_drm_panel_alloc(), the call unconditionally used desc->connector_type instead, ignoring the computed fallback and potentially passing DRM_MODE_CONNECTOR_Unknown, which drm_panel_bridge_add() does not allow. Move the connector_type validation / fallback logic before the devm_drm_panel_alloc() call and pass the computed connector_type to devm_drm_panel_alloc(), so panels without an explicit connector_type once again get the DPI default.

The connector type for the DataImage SCF0700C48GGU18 panel is missing and devm_drm_panel_bridge_add() requires connector type to be set. This leads to a warning and a backtrace in the kernel log and panel does not work: " WARNING: CPU: 3 PID: 38 at drivers/gpu/drm/bridge/panel.c:379 devm_drm_of_get_bridge+0xac/0xb8 " The warning is triggered by a check for valid connector type in devm_drm_panel_bridge_add(). If there is no valid connector type set for a panel, the warning is printed and panel is not added. Fill in the missing connector type to fix the warning and make the panel operational once again.

2026-01-13drm/panel: mantix: Improve power off sequenceSebastian Krzyszkowiak
According to the sequence from section 7.3.4 of FT8006P datasheet, TP_RSTN and RESX should be asserted after disabling AVDD and AVEE and together with VDDI. Also, AVEE power down needs to happen at least 150ms after entering sleep mode.

2026-01-13drm/panel: mantix: Improve power on sequence timingsSebastian Krzyszkowiak
FP8006P datasheet mentions: > It is necessary to wait 15msec after releasing RESX before sending > commands. Also Sleep Out command cannot be sent for 120 msec. This hasn't been respected by the driver so far, which could interfere with the LCD init code sequence performed by the controller. In some cases this leads to VCOM voltage being set to a wrong value, causing "halo" effects, temporary burn-in around the edges of the screen and degraded image contrast. T3 and T4 are counted from when VDDI is enabled. There's no need to add them when we've already waited more than that in T2 and T2d. While FT8006P datasheet does not mention a delay between exiting sleep mode and turning the display on, code provided by the vendor uses 120ms there and it happens to be the same value as required in newer datasheets for newer controllers from the same family, so it seems appropriate to use it here as well.

2026-01-13drm/panel: Fix a possible null-pointer dereference in jdi_panel_dsi_remove()Tuo Li
In jdi_panel_dsi_remove(), jdi is explicitly checked, indicating that it may be NULL: if (!jdi) mipi_dsi_detach(dsi); However, when jdi is NULL, the function does not return and continues by calling jdi_panel_disable(): err = jdi_panel_disable(&jdi->base); Inside jdi_panel_disable(), jdi is dereferenced unconditionally, which can lead to a NULL-pointer dereference: struct jdi_panel *jdi = to_panel_jdi(panel); backlight_disable(jdi->backlight); To prevent such a potential NULL-pointer dereference, return early from jdi_panel_dsi_remove() when jdi is NULL.

2025-12-16drm/panel: otm8009a: Switch to mipi_dsi_multi_context helpersAmin GATTOUT
Update the driver to use the non-deprecated mipi_dsi_*_multi() helpers, as recommended in Documentation/gpu/todo.rst. The multi variants provide proper error accumulation and handle the required DCS NOP insertions, which suits the OTM8009A command sequences. Refactor otm8009a_dcs_write_buf() and the dcs_write_seq/dcs_write_cmd_at macros to take a mipi_dsi_multi_context pointer, passing it through from callers. This ensures consistent error handling throughout the driver. Replace all mdelay() and msleep() calls within DSI command sequences with mipi_dsi_msleep() for proper error accumulation. The init, disable, and backlight update paths now return dsi_ctx.accum_err, ensuring errors are propagated to callers.
