[PATCH] RDMA/rds: Remove duplicate MODULE_LICENSE() from ib.c

[PATCH] RDMA/rds: Remove duplicate MODULE_LICENSE() from ib.c

[Jeff Johnson]

Since commit 1fffe7a34c89 ("script: modpost: emit a warning when the
description is missing"), a module without a MODULE_DESCRIPTION() will
result in a warning with make W=1. One strategy for identifying such
modules is to search for files which have a MODULE_LICENSE() but which
do not have a MODULE_DESCRIPTION(). net/rds/ib.c is one such file. And
its product, ib.o, is a component of the rds_rdma module via:

obj-$(CONFIG_RDS_RDMA) += rds_rdma.o
rds_rdma-y :=	rdma_transport.o \
			ib.o ib_cm.o ib_recv.o ib_ring.o ib_send.o ib_stats.o \
			ib_sysctl.o ib_rdma.o ib_frmr.o

Interestingly, when CONFIG_RDS_RDMA=m, the missing description warning
is NOT emitted by modpost. This is because rdma_transport.c contains a
MODULE_DESCRIPTION() that describes this module. And in addition,
rdma_transport.c contains a MODULE_LICENSE() for this module.

Since rdma_transport.c already contains both the MODULE_LICENSE() and
the MODULE_DESCRIPTION() for the rds_rdma module, remove the duplicate
MODULE_LICENSE() from ib.c

The title of the patch is wrong, it should be "net/rds: Remove duplicate MODULE_LICENSE() from ib.c"

Thanks
