When writing some udev rules using the input system's modalias
attribute, udevinfo showed it as being ignored. Debugging revealed the
52 character string was over 128 bytes long according to udev (and hence
ignored).
The problem appears to be in the kernel where a max_t in input.c should
really be a min_t.
