Subject: [PATCH] drm/bridge: display-connector: fix an uninitialized pointer in probe()
Git-commit: 189723fbe9aca18d6f7d638c59a40288030932b5
Patch-mainline: v5.17-rc1
References: git-fixes

The "label" pointer is used for debug output.  The code assumes that it
is either NULL or valid, but it is never set to NULL.  It is either
valid or uninitialized.
