Subject: [PATCH for-next 1/4] RDMA/hns: Remove unused parameter udata
Date: Wed, 12 May 2021 16:12:19 +0800	[thread overview]
Message-ID: <1620807142-39157-2-git-send-email-liweihang@huawei.com> (raw)
In-Reply-To: <1620807142-39157-1-git-send-email-liweihang@huawei.com>

From: Lang Cheng <chenglang@huawei.com>

The old version of ib_umem_get() need these udata as a parameter but now
they are unnecessary.

Fixes: c320e527e154 ("IB: Allow calls to ib_umem_get from kernel ULPs")
