+Subject: [PATCH] backport-include: fix linux/acpi_amd_wbrf.h inclusion
+
+Fix building for kernel >= 6.8 by adjusting incorrect guard usage,
+otherwise an #include_next header is masked and compilation will fail
+for net/mac80211/wbrf.c in the mac80211 kernel module.
+
+Fixes: 52cdcaab ("backport-include: backport linux/acpi_amd_wbrf.h")
