From 0546858c59fb90122ca8c820e6aa221925a13bd8 Mon Sep 17 00:00:00 2001 From: Yufen Yu Date: Thu, 8 Oct 2020 23:26:32 -0400 Subject: block: get rid of unnecessary local variable Since whole elevator register is protectd by sysfs_lock, we don't need extras 'has_elevator'. Just use q->elevator directly.
