Subject: [PATCH AUTOSEL 5.15 08/24] s390/debug: add _ASM_S390_ prefix to header guard

From: Niklas Schnelle <schnelle@...ux.ibm.com>

[ Upstream commit 0d4d52361b6c29bf771acd4fa461f06d78fb2fac ]

Using DEBUG_H without a prefix is very generic and inconsistent with
other header guards in arch/s390/include/asm. In fact it collides with
the same name in the ath9k wireless driver though that depends on !S390
via disabled wireless support. Let's just use a consistent header guard
name and prevent possible future trouble.
