[dpdk-stable] patch 'crypto/armv8: fix clang build' has been queued to LTS release 18.11.7

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/20. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/8417ae2c5242dbf4c8d549121df01196d84adebd

Thanks.

Kevin.

Subject: [PATCH] crypto/armv8: fix clang build

[ upstream commit 94b686e5026e2612038b8ea5382e22729553738a ]

1. Clang requires braces around initialization of subobject.
2. Clang complains implicit conversion of enumeration type.

Trapped issue with Clang version 8.0 and CONFIG_RTE_LIBRTE_PMD_ARMV8_CRYPTO
was set.
Error messages:
rte_armv8_pmd.c:144:2: error: suggest braces around initialization of
 subobject [-Werror,-Wmissing-braces]
        NULL
        ^~~~
        {   }
/usr/lib/llvm-8/lib/clang/8.0.0/include/stddef.h:105:16: note: expanded
 from macro 'NULL'
               ^~~~~~~~~~
rte_armv8_pmd.c:429:21: error: implicit conversion from enumeration
 type 'enum rte_crypto_cipher_operation' to different enumeration type
      'enum armv8_crypto_cipher_operation' [-Werror,-Wenum-conversion]
        cop = sess->cipher.direction;
            ~ ~~~~~~~~~~~~~^~~~~~~~~
