Subject: [PATCH] RDMA/rtrs: server: Fix error handling in get_or_create_srv
Date: Tue,  4 Nov 2025 10:19:00 +0800	[thread overview]
Message-ID: <20251104021900.11896-1-make24@iscas.ac.cn> (raw)

get_or_create_srv() fails to call put_device() after
device_initialize() when memory allocation fails. This could cause
reference count leaks during error handling, preventing proper device
cleanup and resulting in memory leaks.

Found by code review.

Cc: stable@vger.kernel.org
Fixes: 9cb837480424 ("RDMA/rtrs: server: main functionality")
