commit: 57d7e98d0257bd9795dd3f438d19aa5476554685 [2114/2687] drm/amdkcl: Test 
whether drm_{mm_print/debug_printer} is available
config: i386-allyesconfig (attached as .config)
compiler: gcc-7 (Debian 7.5.0-3) 7.5.0
reproduce:
        git checkout 57d7e98d0257bd9795dd3f438d19aa5476554685
        # save the attached .config to linux build tree
        make ARCH=i386
