Subject: [PATCH] IB: Revert "remove redundant INFINIBAND kconfig dependencies"
Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends
on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a
link error when another driver using it is built-in. The
INFINIBAND_ADDR_TRANS dependency is insufficient here as this is
a 'bool' symbol that does not force anything to be a module in turn.
fs/cifs/smbdirect.o: In function `smbd_disconnect_rdma_work':
smbdirect.c:(.text+0x1e4): undefined reference to `rdma_disconnect'
net/9p/trans_rdma.o: In function `rdma_request':
