[PATCH 3/4] qemu-img: remove unused variable |
Date: |
Wed, 9 Nov 2022 10:57:13 -0500 |
From: Miroslav Rezanina <mrezanin@redhat.com>
Variable block_count used in img_dd function is only incremented but never read.
This causes 'Unused but set variable' warning on Clang 15.0.1 compiler.
Removing the variable to prevent the warning.
