IMO, it is untidy to move just this little << 1 piece to another line.
I've amended this part and made it look like:

                        mtd->erasesize = (128 * 1024);
                        mtd->erasesize <<= ((id_data[3] & 0x03) << 1);

instead, if you do not mind, and pushed to l2-mtd-2.6.git / master,
thanks!
