drm/imx/tve: fix probe device leak

2026-02-06T15:55:47+00:00

commit e535c23513c63f02f67e3e09e0787907029efeaf upstream. Make sure to drop the reference taken to the DDC device during probe on probe failure (e.g. probe deferral) and on driver unbind.

drm/imx/ipuv3: Use IRQF_NO_AUTOEN flag in request_irq()

2024-12-05T13:01:38+00:00

[ Upstream commit 40004709a3d3b07041a473a163ca911ef04ab8bd ] disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.

Revert "drm: Make drivers depends on DRM_DW_HDMI"

2024-05-02T15:59:59+00:00

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

drm: Make drivers depends on DRM_DW_HDMI

2024-03-28T10:26:49+00:00

DRM_DW_HDMI has a number of dependencies that might not be enabled. However, drivers were used to selecting it while not enforcing the DRM_DW_HDMI dependencies. This could result in Kconfig warnings (and further build breakages) such as: Kconfig warnings: (for reference only) WARNING: unmet direct dependencies detected for DRM_DW_HDMI Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && DRM_DISPLAY_HELPER [=n] Selected by [m]: - DRM_SUN8I_DW_HDMI [=m] && HAS_IOMEM [=y] && DRM_SUN4I [=m] Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202403262127.kZkttfNz-lkp@intel.com/ Acked-by: Jani Nikula Link: https://lore.kernel.org/r/20240327-kms-kconfig-helpers-v3-7-eafee11b84b3@kernel.org Signed-off-by: Maxime Ripard

The .get_modes() hooks aren't supposed to return negative error codes. Return 0 for no modes, whatever the reason.
