[PATCH 2/5] selinux: use correct type for context length

From: Christian Göttsche
Date: Thu Feb 17 2022 - 09:21:52 EST


security_sid_to_context() expects a pointer to an u32 as the address
where to store the length of the computed context.

Reported by sparse:

security/selinux/xfrm.c:359:39: warning: incorrect type in argument 4 (different signedness)
security/selinux/xfrm.c:359:39: expected unsigned int [usertype] *scontext_len
security/selinux/xfrm.c:359:39: got int *
