--------------------------------
commit dcaa86b904ea3761e62c849957dd0904e126bf4a upstream.
Make ASYMMETRIC_PUBLIC_KEY_SUBTYPE select CRYPTO_SIG to avoid build errors like the following, which were possible with CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE=y && CONFIG_CRYPTO_SIG=n:
ld: vmlinux.o: in function `public_key_verify_signature': (.text+0x306280): undefined reference to `crypto_alloc_sig' ld: (.text+0x306300): undefined reference to `crypto_sig_set_pubkey' ld: (.text+0x306324): undefined reference to `crypto_sig_verify' ld: (.text+0x30636c): undefined reference to `crypto_sig_set_privkey'
