Keep your changes small until you really know how this
style of linux kernel staging changes is done.

A patch series is much preferred to a single large change.

If you decide to refactor various functions, please do that
in separate, discrete patches.

Adding a #define and doing a sed like:

$ sed -i 's/(BY_AL2230_REG_LEN << 3) + IFREGCTL_REGW/AL2230_RLEN_CTL/' drivers/staging/vt6655/*.[ch]

should be a single patch.

And if you do that, another should be done for AL7230

$ sed -i 's/(BY_AL7230_REG_LEN << 3) + IFREGCTL_REGW/AL7230_RLEN_CTL/' drivers/staging/vt6655/*.[ch]

etc...

Maybe the #define BY_AL2230_REG_LEN should be 0x17 so that
the << 3 is more obviously constrained to the low byte

Maybe the + uses in the macros should be bitwise |.

Go wild after you figure out the process, just keep your
patches to obvious, small and verifiable changes.
