media: platform: amd: fix unmet dependency for VIDEO_V4L2_SUBDEV_API

[PATCH] media: platform: amd: fix unmet dependency for VIDEO_V4L2_SUBDEV_API

Posted by Julian Braha 1 week, 6 days ago

Currently, VIDEO_AMD_ISP4_CAPTURE selects VIDEO_V4L2_SUBDEV_API without
ensuring MEDIA_CONTROLLER is enabled, causing an unmet dependency:

WARNING: unmet direct dependencies detected for VIDEO_V4L2_SUBDEV_API
  Depends on [n]: MEDIA_SUPPORT [=m] && VIDEO_DEV [=m] && MEDIA_CONTROLLER [=n]
  Selected by [m]:
  - VIDEO_AMD_ISP4_CAPTURE [=m] && MEDIA_SUPPORT [=m] && MEDIA_PLATFORM_SUPPORT [=y] && MEDIA_PLATFORM_DRIVERS [=y] && DRM_AMDGPU [=m] && DRM_AMD_ISP [=y] && HAS_DMA [=y] && VIDEO_DEV [=m]

Many other options in this subsystem select MEDIA_CONTROLLER, let's do the
same here.

This unmet dependency bug was detected by kconfirm, a static analysis tool
for Kconfig.
