[dpdk-dev] [PATCH] crypto/qat: fix second seg fault in QAT PMD

[Bernard Iremonger]

While running the IPsec unit tests the following
segmentation fault is occurring:

Thread 1 "test" received signal SIGSEGV, Segmentation fault.
0x0000000000bf3b50 in qat_sym_process_response (
op=0x5355280 <unittest_params+512>, resp=0x100455100 "")
at /root/dpdk/drivers/crypto/qat/qat_sym.h:161
161	if (sess->bpi_ctx)

Fixes: 91614c73b67c ("crypto/qat: make response process function inline")
