[PATCH 5.11 005/152] fs: nfsd: fix kconfig dependency warning for NFSD_V4

[Greg Kroah-Hartman]

From: Julian Braha <julianbraha@xxxxxxxxx>

[ Upstream commit 7005227369079963d25fb2d5d736d0feb2c44cf6 ]

When NFSD_V4 is enabled and CRYPTO is disabled,
Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for CRYPTO_SHA256
  Depends on [n]: CRYPTO [=n]
  Selected by [y]:
  - NFSD_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFSD [=y] && PROC_FS [=y]

WARNING: unmet direct dependencies detected for CRYPTO_MD5
  Depends on [n]: CRYPTO [=n]
  Selected by [y]:
  - NFSD_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFSD [=y] && PROC_FS [=y]

This is because NFSD_V4 selects CRYPTO_MD5 and CRYPTO_SHA256,
without depending on or selecting CRYPTO, despite those config options
being subordinate to CRYPTO.
