WARNING: storage class should be at the beginning of the declaration
#51: FILE: drivers/acpi/apei/ghes.c:951:
+inline static void ghes_init_nmi(void)

ERROR: inline keyword should sit between storage class and type
#51: FILE: drivers/acpi/apei/ghes.c:951:
+inline static void ghes_init_nmi(void)

i.e..

static inline void ...
