Guys, I think that simple ((dev->variant->version & 0xF0) == 0x70) would cover every 7.x version. Same could apply to versions 6.x and 5.x. Then instead of using IS_MFCV6_PLUS(dev) one would use IS_MFCV6(dev) || IS_MFCV7(dev). This is a bit longer, but if version 8 will be totally different from v7 then it is much better to use v6||v7 instead of v6_plus.
