block: drop dead assignments in loop_init()
Commit 8410d38c ("loop: use __register_blkdev to allocate devices on demand") simplified loop_init(); so computing the range of the block region is not required anymore and can be dropped. Drop dead assignments in loop_init(). As compilers will detect these unneeded assignments and optimize this, the resulting object code is identical before and after this change. No functional change. No change in object code. Signed-off-by: Lukas Bulwahn <lukas.bulwahn@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
