Subject: [PATCH v3 5/6] net: hns3: Remove io_stop_wc() calls after __iowrite64_copy()
Date: Thu, 11 Apr 2024 13:46:18 -0300 [thread overview]
Message-ID: <5-v3-1893cd8b9369+1925-mlx5_arm_wc_jgg@nvidia.com> (raw)
In-Reply-To: <0-v3-1893cd8b9369+1925-mlx5_arm_wc_jgg@nvidia.com>
Now that the ARM64 arch implementation does the DGH as part of
__iowrite64_copy() there is no reason to open code this in drivers.
