[PATCH 0/6] use gpio-cascade for Buffalo WZR-HP-G300NH

[Mauri Sandberg]

Currently, Buffalo wzr-hp-g300nh uses a driver that is developed specificly
for NXP 74HC153 dual 4-way multiplexer. It's being used for several different
buttons on the device casing. Replace that driver with a generic gpio-cascade
driver that is in the process of being upstreamed.

All comments are welcome but I would need someone to have a look at the
AUTOLOAD clauses in the kernel package makefiles. The way they are
specified currently allows loading modules early enough for using the
reset key for entering the failsafe. Nevertheless, it's a copypaste without
much understanding what goes where and there could be room for improvements.

Thanks,
Mauri
