Simply do:
# crash vmcore vmlinux
crash> sym -M
c008000007810000 MODULE START: crc32c_vpmsum
c008000007810000 (^R) __crc32c_vpmsum
c008000007810670 (^B) crc32c_vpmsum_cra_init
But cmd_mod() seems to be doing right thing:
crash> mod -s crc32c_vpmsum
crash> sym -M
c008000007810000 MODULE START: crc32c_vpmsum
c008000007810000 (T) __crc32c_vpmsum
c008000007810670 (t) crc32c_vpmsum_cra_init

Yes Steve's patch fixes trace segfault for me.
