Subject[PATCH 2/2] staging: vt6655: Replace VNSvInPortB with ioread8
Replace macro VNSvInPortB with ioread8. Avoid cast of the return
value is possible with one exception.
The name of macro and the arguments use CamelCase which
is not accepted by checkpatch.pl

Since there are more than one checkpatch issue per line,
more steps are rquired to fix.

Signed-off-by: Philipp Hortmann <philipp.g.hortmann@gmail.com>

V1 -> V2: This patch was 4/7 and is now 3/6
V2 -> V3: Changed from rename macro arguments to replace
macro VNSvInPortB with ioread8
This patch was 3/6 and is now 1/7
V3 -> V4: Replacement now without a cast of the return value with
only one exception.

Note: The one casting exception could be removed by changing
bb_read_embedded. Instead of having a unused return value bool
the return value could be an unsigned char.
