[PATCH 5.13 295/300] IMA: remove -Wmissing-prototypes warning

[Greg Kroah-Hartman]

From: Austin Kim <austin.kim@xxxxxxx>

commit a32ad90426a9c8eb3915eed26e08ce133bd9e0da upstream.

With W=1 build, the compiler throws warning message as below:

   security/integrity/ima/ima_mok.c:24:12: warning:
   no previous prototype for ‘ima_mok_init’ [-Wmissing-prototypes]
       __init int ima_mok_init(void)

Silence the warning by adding static keyword to ima_mok_init().
