Subject: Btrfs: fix error return code in btrfs_init_test_fs()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04e1b65af2085d4102b2b5d2fd1e050f8ee63092;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: fix error return code in btrfs_init_test_fs()

Fix to return a negative error code from the kern_mount() error handling
case instead of 0(ret is set to 0 by register_filesystem), as done
elsewhere in this function.
