From aeb2b0b1a3da5791d3b216e71ec72db7570f3571 Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Sat, 12 Dec 2020 06:13:02 +0100 Subject: block: drop dead assignments in loop_init() Commit 8410d38c2552 ("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.
