You are right, the double quotes makes the difference here.

$ modules_output=$(awk '{print $1, $2, $3}' /proc/modules | sort)

$ echo $modules_output
bluetooth 320499 5 btbcm 5506 1 btintel 2739 1 ...

$ echo "$modules_output"
bluetooth 320499 5
btbcm 5506 1
btintel 2739 1
...


Consider the patch acked then.
