From 2815a277c53e9a84784d6410cd55a9da5b33068d Mon Sep 17 00:00:00 2001 From: Ruoyu Wang Date: Thu, 18 Jun 2026 12:17:51 +0800 Subject: [PATCH] RDMA/erdma: initialize ret for empty receive WR lists erdma_post_recv() returns ret after walking the receive work request list. If the caller passes an empty list, the loop is skipped and ret is not assigned. Initialize ret to 0 so an empty receive work request list returns success instead of stack data.
