In v2.4.0-test2pre2 mmc_ioctl_cdrom_read_data() was extended by issuing a MODE_SELECT opcode to change the sector size and READ_10 to perform the actual read if the READ_CD opcode is not support. The sector size is never changed back to the previous value of 2048 bytes which is however denoted by the comment for version 3.09 of the cdrom.c file. Use cdrom_switch_blocksize() to change the sector size only if the requested size deviates from 2048. Change it back to 2048 after the read operation if a change was mode.
