Subject: [PATCH] KEYS: asymmetric: Add missing dependency on CRYPTO_SIG
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'
Fixes: 63ba4d67594a ("KEYS: asymmetric: Use new crypto interface without scatterlists")
