Hi, Maintainers.
I send this email for fix a kernel warning
`
if (!bridge->container)
DRM_WARN("DRM bridge corrupted or not allocated by
devm_drm_bridge_alloc()\n");
`
I see this warning since 6.18.X, but until 7.1.X, this still unfixed..
I don't have a env to follow kernel patching process, thus write a email, and
leave it as is.
anyone who has interesting to follow up, welcome, you don't have to keep my
name in your patch.
here is the patch:
