[PATCH 07/10] tailq: fix cast macro for null pointer

Doing arithmetics with the NULL pointer is undefined. Caught by UBSan: ../app/test/test_tailq.c:111:9: runtime error: member access within null pointer of type 'struct rte_tailq_head' Fixes: f6b4f6c9c123 ("tailq: use a single cast macro") Cc: sta...@dpdk.org Signed-off-by: David Marchan
