4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>
commit 342e91578eb6909529bc7095964cd44b9c057c4e upstream.
'perms' will never be NULL since it isn't a plain pointer but an array
of u32 values.
This fixes the following warning when building with clang:
security/selinux/ss/services.c:158:16: error: address of array
'p_in->perms' will always evaluate to 'true'
[-Werror,-Wpointer-bool-conversion]
while (p_in->perms && p_in->perms[k]) {
