    DRM: bug: RADEON_DEBUGFS_MAX_{NUM_FILES => COMPONENTS} · c245cb9e

    The value of RADEON_DEBUGFS_MAX_NUM_FILES has been used to
    specify the size of an array, each element of which looks
    like this:
    
      struct radeon_debugfs {
              struct drm_info_list    *files;
              unsigned                num_files;
      };
    
    Consequently, the number of debugfs files may be much greater
    than RADEON_DEBUGFS_MAX_NUM_FILES, something that the current
    code ignores:
    
      if ((_radeon_debugfs_count + nfiles) > RADEON_DEBUGFS_MAX_NUM_FILES) {
              DRM_ERROR("Reached maximum number of debugfs files.\n");
              DRM_ERROR("Report so we increase RADEON_DEBUGFS_MAX_NUM_FILES.\n");
              return -EINVAL;
      }
    
    This commit fixes this make, and accordingly renames:
    
      RADEON_DEBUGFS_MAX_NUM_FILES
    
    to:
    
      RADEON_DEBUGFS_MAX_COMPONENTS
