All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0xd102d6): Section mismatch in reference from the function __of_remove_property_sysfs() to the variable .init.text:.L0
The function __of_remove_property_sysfs() references
the variable __init .L0 .
This is often because __of_remove_property_sysfs lacks a __init
annotation or the annotation of .L0 is wrong.
--
>> WARNING: modpost: vmlinux.o(.text+0xd10312): Section mismatch in reference from the function __of_update_property_sysfs() to the variable .init.text:.L0
The function __of_update_property_sysfs() references
the variable __init .L0 .
This is often because __of_update_property_sysfs lacks a __init
annotation or the annotation of .L0 is wrong.
--
>> WARNING: modpost: vmlinux.o(.text+0xdc7e28): Section mismatch in reference from the function mcb_bus_put() to the variable .exit.text:.L0
The function mcb_bus_put() references a variable in an exit section.
Often the variable .L0 has valid usage outside the exit section
and the fix is to remove the __exit annotation of .L0 .
