Bug in a resume module script

Hey everyone,

I'm using Void Linux and if I have the resume module activated, I get a message early on boot saying:
  //lib/dracut/hooks/pre-mount/10-resume.sh: line 20: echo: write error: Invalid argument

I managed to fix this with a small adjustment to /usr/lib/dracut/modules.d/95resume/resume.sh:
  20c20
  < echo "${maj%,}:$min"> /sys/power/resume)
  ---
  > echo $maj:$min | tr -d , > /sys/power/resume)

Never had to submit a bug to such a big project, so I'm not sure if this is the place to do it.
