Subject: crypto/zuc: fix build with GCC 11
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=099db3d156038b792d97c29a6e2743369d7d50a5;p=dpdk.git

crypto/zuc: fix build with GCC 11

GCC 11 complains that some arrays may be uninitialized in
process_zuc_hash_op(). This is because their initialization
depends on num_ops being > 0.

This function is only called with num_ops > 0 because of
checks in process_zuc_hash_op().

To remove the warning initialize the arrays.

Fixes: 0b133c36ad7d ("crypto/zuc: support IPsec Multi-buffer lib v0.54")
