[Pm-utils] [patch] fix modunload function

[Stefan Seyfried]

Hi,

modunload currently does not unload anything but "pcmcia" for me.
I'm not sure why this is happening, maybe it is even a bug in my
bash, since

root at strolchi:/# A=button
root at strolchi:/# B=$A
root at strolchi:/# [[ "$A" =~ "$B" ]] || echo hello
hello

looks strange. However, i also think my code is simpler and cleaner:
