It's a bit hard to tell without knowing more details about the problem you have. I guess your problem is that originally the functions were passed struct inode * and struct file * while now they are passed struct block_device and fmode_t. That should be fairly easy to solve as most drivers use just inode->i_bdev (now passed directly) and file->f_flags (also passed directly in the new convention). You can have a look e.g. at commit 0338e29178795f0df0e1f3705b5d3effe9c95ff7 where drivers/scsi/sd.c is converted.
