retitle 346460 evdev driver broken on big-endian machines
tags 346460 + patch
thanks
This bug is not fixed, it still is in 6.9.0.dfsg.1-4.
I had same time to look into the problem: The current evdev driver
doesn't work on big-endian machines. Here's patch that fixes that
by using the macros from Vojtech Pavlik's evtest.c.
