From 490a253cb4893043266622f24153026d454abcdb Mon Sep 17 00:00:00 2001 From: Qianfeng Rong Date: Tue, 26 Aug 2025 23:05:56 +0800 Subject: [PATCH] RDMA/rdmavt: Use int type to store negative error codes Change 'ret' from u32 to int in alloc_qpn() to store -EINVAL, and remove the 'bail' label as it simply returns 'ret'. Storing negative error codes in an u32 causes no runtime issues, but it's ugly as pants, Change 'ret' from u32 to int type - this change has no runtime impact.
