This is often because devfreq_remove_device lacks a __init annotation or the annotation of .LBB192 is wrong. -- The function iio_device_free() references the variable __init .LBB228. This is often because iio_device_free lacks a __init annotation or the annotation of .LBB228 is wrong. -- FATAL: modpost: The relocation at __ex_table+0xd88 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.
