staging: dgnc: clean up dgnc_input function
This is for fixing checkpatch.pl warning about "Alignment should match open parenthesis" but if that is fixed, code line is over 80 characters. I think "ch->ch_rqueue + tail + i" could be declared once in the begining of loop. Signed-off-by: Daeseok Youn <daeseok.youn@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
