If you fix the issue, kindly add following tag as appropriate

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

>> WARNING: modpost: vmlinux.o(.text+0x179120): Section mismatch in reference from the function do_init_module() to the function .init.text:ftrace_boot_snapshot()
The function do_init_module() references
the function __init ftrace_boot_snapshot().
This is often because do_init_module lacks a __init
annotation or the annotation of ftrace_boot_snapshot is wrong.
