Subject: [PATCH 1/2] firmware: stratix10-svc: add missing gen_pool_destroy() in stratix10_svc_drv_probe()
Date: Tue, 29 Nov 2022 10:36:01 -0600 [thread overview]
Message-ID: <20221129163602.462369-1-dinguyen@kernel.org> (raw)
From: Yang Yingliang <yangyingliang@huawei.com>
In error path in stratix10_svc_drv_probe(), gen_pool_destroy() should be called
to destroy the memory pool that created by svc_create_memory_pool().
Fixes: 7ca5ce896524 ("firmware: add Intel Stratix10 service layer driver")
