Subject: [PATCH] firmware: stratix10-svc: Fix IS_ERR() vs NULL check in stratix10_svc_drv_probe()
Date:   Mon, 14 Nov 2022 10:59:21 +0800
Message-ID: <20221114025921.1194834-1-cuigaosheng1@huawei.com>
MIME-Version: 1.0

Precedence: bulk

The svc_create_memory_pool() returns an ERR_PTR() on failure, we should use
IS_ERR() to check the return value, and return it on failure.

Fixes: 7ca5ce896524 ("firmware: add Intel Stratix10 service layer driver")
