Applied, thank you.

[PATCH] chelsio/chtls: Re-add dependencies on CHELSIO_T4 to fix modular CHELSIO_T4

[Geert Uytterhoeven]

As CHELSIO_INLINE_CRYPTO is bool, and CHELSIO_T4 is tristate, the
dependency of CHELSIO_INLINE_CRYPTO on CHELSIO_T4 is not sufficient to
protect CRYPTO_DEV_CHELSIO_TLS and CHELSIO_IPSEC_INLINE.  The latter two
are also tristate, hence if CHELSIO_T4=n, they cannot be builtin, as
that would lead to link failures like:

drivers/net/ethernet/chelsio/inline_crypto/chtls/chtls_main.c:259: 
undefined reference to `cxgb4_port_viid'

and

drivers/net/ethernet/chelsio/inline_crypto/ch_ipsec/chcr_ipsec.c:752: 
undefined reference to `cxgb4_reclaim_completed_tx'

Fix this by re-adding dependencies on CHELSIO_T4 to tristate symbols.
The dependency of CHELSIO_INLINE_CRYPTO on CHELSIO_T4 is kept to avoid
asking the user.

Fixes: 6bd860ac1c2a0ec2 ("chelsio/chtls: CHELSIO_INLINE_CRYPTO should depend on 
CHELSIO_T4")
