Subject: Btrfs: check error before reporting missing device and add uuid
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=33b97e43279a60729eee502809cf5269b3a64cf3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: check error before reporting missing device and add uuid

Report missing device when add is successful,
otherwise it would exit as ENOMEM. And add uuid
to the report.
