Because the first patch modifies the struct public_key and removes the MPIs from it,
which the code modified in the second patch still uses. If bisect only takes the first
then the build will fail on the security/integrity/digsig_asymmetric.c as reported by
kbuild test robot:

>> security/integrity/digsig_asymmetric.c:95:5: error: 'struct public_key_signature' has no member named 'nr_mpi'
     pks.nr_mpi = 1;
