Subject: [PATCH 15/19] net: dsa: restrict SMSC_LAN9303_I2C kconfig
Git-commit: 0a3ad7d323686fbaae8688326cc5ea0d185c6fca
Patch-mainline: v5.19-rc1
References: git-fixes
Since kconfig 'select' does not follow dependency chains, if symbol KSA
selects KSB, then KSA should also depend on the same symbols that KSB
depends on, in order to prevent Kconfig warnings and possible build
errors.
Change NET_DSA_SMSC_LAN9303_I2C and NET_DSA_SMSC_LAN9303_MDIO so that
they are limited to VLAN_8021Q if the latter is enabled. This prevents
the Kconfig warning:
WARNING: unmet direct dependencies detected for NET_DSA_SMSC_LAN9303
Depends on [m]: NETDEVICES [=y] && NET_DSA [=y] && (VLAN_8021Q [=m] || VLAN_8021Q [=m]=n)
Selected by [y]:
- NET_DSA_SMSC_LAN9303_I2C [=y] && NETDEVICES [=y] && NET_DSA [=y] && I2C [=y]
