# Special target that causes drm2 code to printf error returns.  Useful for
# determining the root cause of errors.  Depends on drmP.h macro DRM_ERR_RET.
# After running this target, set the ENABLE_DRM_ERR_RET make variable.
# A few files don't support this mechanism, so just exclude them.
#
# WARNING: THIS WILL CHANGE THE SOURCE TREE!  ONLY USE IF THERE ARE NO OTHER
#          CHANGES THAT NEED TO BE RECOVERED!
