This is often because led_set_brightness_sync lacks a __init annotation or the annotation of .LBE1384 is wrong. -- The function led_set_brightness_nosleep() references the variable __init .LBE1486. This is often because led_set_brightness_nosleep lacks a __init annotation or the annotation of .LBE1486 is wrong. -- FATAL: modpost: The relocation at __ex_table+0xf38 references section ".debug_str" which is not executable, IOW it is not possible for the kernel to fault at that address. Something is seriously wrong and should be fixed. --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
