This breaks the SMP=n build:
drivers/misc/cxl/guest.c: In function 'attach_afu_directed':
drivers/misc/cxl/guest.c:572:12: error: 'H_SUCCESS' undeclared (first use in
this function)
drivers/misc/cxl/guest.c:572:12: note: each undeclared identifier is reported
only once for each function it appears in
I've fixed it up with:
