Janne Grunau 43eb647e84 drm: Select DRM_KMS_HELPER from DRM_DEBUG_DP_MST_TOPOLOGY_REFS 
commit 32dce6b194 upstream.

Using "depends on" and "select" for the same Kconfig symbol is known to
cause circular dependencies (cmp. "Kconfig recursive dependency
limitations" in Documentation/kbuild/kconfig-language.rst.
DRM drivers are selecting drm helpers so do the same for
DRM_DEBUG_DP_MST_TOPOLOGY_REFS.
Fixes following circular dependency reported on x86 for the downstream
Asahi Linux tree:

error: recursive dependency detected!
  symbol DRM_KMS_HELPER is selected by DRM_GEM_SHMEM_HELPER
  symbol DRM_GEM_SHMEM_HELPER is selected by RUST_DRM_GEM_SHMEM_HELPER
  symbol RUST_DRM_GEM_SHMEM_HELPER is selected by DRM_ASAHI
  symbol DRM_ASAHI depends on RUST
  symbol RUST depends on CALL_PADDING
  symbol CALL_PADDING depends on OBJTOOL
  symbol OBJTOOL is selected by STACK_VALIDATION
  symbol STACK_VALIDATION depends on UNWINDER_FRAME_POINTER
  symbol UNWINDER_FRAME_POINTER is part of choice block at arch/x86/Kconfig.debug:224
  symbol <choice> unknown is visible depending on UNWINDER_GUESS
  symbol UNWINDER_GUESS prompt is visible depending on STACKDEPOT
  symbol STACKDEPOT is selected by DRM_DEBUG_DP_MST_TOPOLOGY_REFS
  symbol DRM_DEBUG_DP_MST_TOPOLOGY_REFS depends on DRM_KMS_HELPER

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
