From ec9fd2a13d743ae129bd1b5c6edea0d65260ce10 Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Tue, 15 Feb 2022 03:52:47 -0800 Subject: blk-lib: don't check bdev_get_queue() NULL check Based on the comment present in the bdev_get_queue() bdev->bd_queue can never be NULL. Remove the NULL check for the local variable q that is set from bdev_get_queue() for discard, write_same, and write_zeroes.
