Don't know how proper it is, but a "git grep iminor drivers/" shows that minor = iminor(file_inode(file)); is a very common construct. Or alternatively, do the iminor(inode) lookup once in open() to lookup up your device struct or whatever, and then save that reference in file->private_data, thereby avoiding the need to know the minor anywhere else.
