[PATCH 0/3] staging: vt6655: Replace macro VNSvInPortD with ioread32()

[Philipp Hortmann]

Replace macro VNSvInPortD with ioread32.
Avoid cast of the return value as much as possible.
The name of macro and the arguments use CamelCase which
is not accepted by checkpatch.pl

This patch series is new but patches have been send before.
Review changelog on each patch.

Tested with vt6655 on mini PCI Module
Transferred this patch over wlan connection of vt6655

Used this code for testing of fuction: CARDbGetCurrentTSF in patch
"staging: vt6655: Replace VNSvInPortD with ioread32":
	VNSvInPortD(iobase + MAC_REG_TSFCNTR, (u32 *)pqwCurrTSF);
	VNSvInPortD(iobase + MAC_REG_TSFCNTR + 4, (u32 *)pqwCurrTSF + 1);
	dev_info(&priv->pcid->dev, "CARDbGetCurrentTSF *pqwCurrTSF: %llx", *pqwCurrTSF);
	
	low = ioread32(iobase + MAC_REG_TSFCNTR);
	high = ioread32(iobase + MAC_REG_TSFCNTR + 4);
	dev_info(&priv->pcid->dev, "CARDbGetCurrentTSF temp_ph: %llx",
			 low + ((u64)high << 32));

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.

There is no "v2" in the subject lines in this thread anywhere :(

git will create it automatically for you if you use the '-v' option to
git format-patch.

Please fix up and send a v3 series.
