After applying the patch the file was like:
        /*
   * Scatter-gather buffers (all but the last) must have a length
         * divisible by the bulk maxpacket size.  Otherwise a data packet
         * would end up being short, causing a premature end to the data
         * transfer.  Since high-speed bulk pipes have a maxpacket size

See the alignment of the second line. Please use tab instead of space. And also
checkpatch should have warned you not to use space before the Signed-off-by.
