Reduces the size of drm_kms_helper.ko by ~50%. This patchset is part of an on-going effort to reduce the minimum binary size of the DRM core and helpers. It's helpful for systems with early-boot DRM graphics, which requires DRM to be linked into the kernel image. v2: * move helper library into subdirectory (Jani) * also move DP AUX bus helpers Thomas
