You need to run a patch through checkpatch everytime you change it -
sometimes the warning makes sense, like in this case:

ERROR: do not initialise statics to false
#73: FILE: arch/x86/mm/mem_encrypt.c:45:
+static bool sev_enabled __section(.data) = false;

Please add checkpatch to a script which you run before committing. Or
something to that effect. In any case, you should automate it so that
you don't forget.

Thx.

P.S., just send a fixed version as a reply to this message.
