[dpdk-dev] [PATCH v1] net/avf: fix DEBUG_DUMP_DESC causing build issue

Sun Oct 14 04:34:05 CEST 2018

Add the missed 'volatile' keyword to avoid the warning for type
mismatch, which will be treated as compiler error if WERROR_FLAGS
is enabled.

Fixes: bfd38e4d708b ("net/avf: fix missing compiler error flags")
