When applying the upstream commit 4702c28ac777 [lib/ubsan: Don't seralize UBSAN report] to 4.14 and building with CONFIG_UBSAN, I got a compile error and fixed it as below. Realizing that 4.19 might have the same problem, I checked and found that it did, which this patch fixes. Fixes 4.19-rt commit 73b845faa4ec [lib/ubsan: Don't seralize UBSAN report].
