Merge branch 'bpf-fix-null-deref-when-storing-scalar-into-kptr-slot'
Mykyta Yatsenko says:
====================
bpf: Fix NULL deref when storing scalar into kptr slot
map_kptr_match_type() accesses reg->btf before confirming the register
is PTR_TO_BTF_ID. A scalar store into a kptr slot has no btf, causing
a NULL pointer dereference. Guard base_type() first.
