[Linux-ima-user] [PATCH -next] ima: fix non static symbol warnings

[Wei Y. <wei...@gm...>]

From: Wei Yongjun <wei...@hu...>

Fixes the following sparse warnings:

security/integrity/ima/ima_kexec.c:122:23: warning:
 symbol 'update_buffer_nb' was not declared. Should it be static?
security/integrity/ima/ima_kexec.c:130:6: warning:
 symbol 'ima_add_kexec_buffer' was not declared. Should it be static?
