Subject: [PATCH 5.15 086/110] arm64: kasan: fix include error in MTE functions

From: Paul Semel <semelpaul@...il.com>

commit b859ebedd1e730bbda69142fca87af4e712649a1 upstream.

Fix `error: expected string literal in 'asm'`.
This happens when compiling an ebpf object file that includes
`net/net_namespace.h` from linux kernel headers.

Include trace:
     include/net/net_namespace.h:10
     include/linux/workqueue.h:9
     include/linux/timer.h:8
     include/linux/debugobjects.h:6
     include/linux/spinlock.h:90
