Subject: [PATCH v3 3/3] staging: vt6655: Replace VNSvInPortD with ioread32
Date: Wed, 27 Apr 2022 07:42:23 +0200	[thread overview]
Message-ID: <7a5f7f98379fb2af2741f613f5ddda53e5d4813e.1651036713.git.philipp.g.hortmann@gmail.com> (raw)
In-Reply-To: <cover.1651036713.git.philipp.g.hortmann@gmail.com>

Replace macro VNSvInPortD with ioread32 and as it was
the only user, it can now be removed.
The name of macro and the arguments use CamelCase which
is not accepted by checkpatch.pl

Reported-by: kernel test robot <lkp@intel.com>

V1 -> V2: This patch was 5/7 and is now 4/6
V2 -> V3: Inserted patch that was before in a different way in
          "Rename macros VNSvInPortB,W,D with CamelCase ..."
          This patch was part of 4/6 and is now 3/7
V3 -> V4: Removed casting of the output variable
V4 -> V5: Joint patch "Replace two VNSvInPortD with ioread64_lo_hi"
          with this patch. Changed ioread64 to two ioread32 as
          ioread64 does not work with 32 Bit computers.
          Shorted and simplified patch description.
V5 -> V6: Added missing version in subject
