[Compass-ci] Re: [PATCH lkp-tests] sshd: fix error when execute in docker

• port=$(($(date +%s%N)%"$sshr_port_len"+"$sshr_port_base"))
  

• port=$(($(date +%s%N)%${sshr_port_len}+${sshr_port_base}))
  

style: white space around the operators.

${} is not necessary inside $(( ))

Thanks, Fengguang
