Subject: btrfs: scrub: silence an uninitialized variable warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=07c9a8e07771fce74620aa4f8132537196b8e43a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

btrfs: scrub: silence an uninitialized variable warning

It's basically harmless if "ref_level" isn't initialized since it's only
used for an error message, but it causes a static checker warning.
