It is just a comment, so no changes and silences these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/drm/drm.h' differs from latest version at 'include/uapi/drm/drm.h'

/**
* DRM_IOCTL_MODE_GETFB2 - Get framebuffer metadata.
*
* This queries metadata about a framebuffer. User-space fills
* &drm_mode_fb_cmd2.fb_id as the input, and the kernels fills the rest of the
* struct as the output.
*
* If the client is DRM master or has &CAP_SYS_ADMIN, &drm_mode_fb_cmd2.handles
* will be filled with GEM buffer handles. Planes are valid until one has a
* zero handle -- this can be used to compute the number of planes.
*
* Otherwise, &drm_mode_fb_cmd2.handles will be zeroed and planes are valid
* until one has a zero &drm_mode_fb_cmd2.pitches.
*
* If the framebuffer has a format modifier, &DRM_MODE_FB_MODIFIERS will be set
* in &drm_mode_fb_cmd2.flags and &drm_mode_fb_cmd2.modifier will contain the
* modifier. Otherwise, user-space must ignore &drm_mode_fb_cmd2.modifier.
