Subject: [PATCH -next] rdma/siw: Add missing dependencies on LIBCRC32C and DMA_VIRT_OPS
Date: Wed, 10 Jul 2019 15:39:30 +0200	[thread overview]
Message-ID: <20190710133930.26591-1-geert@linux-m68k.org> (raw)

If LIBCRC32C and DMA_VIRT_OPS are not enabled:

    drivers/infiniband/sw/siw/siw_main.o: In function `siw_newlink':
    siw_main.c:(.text+0x35c): undefined reference to `dma_virt_ops'
    drivers/infiniband/sw/siw/siw_qp_rx.o: In function `siw_csum_update':
    siw_qp_rx.c:(.text+0x16): undefined reference to `crc32c'

Fix the first issue by adding a select of DMA_VIRT_OPS.
Fix the second issue by replacing the unneeded dependency on
CRYPTO_CRC32 by a dependency on LIBCRC32C.

Reported-by: noreply@ellerman.id.au (first issue)
Fixes: c0cf5bdde46c664d ("rdma/siw: addition to kernel build environment")
