Descriptions
In the Linux kernel, the following vulnerability has been resolved: btrfs: add the missing error handling inside get_canonical_dev_path Inside function get_canonical_dev_path(), we call d_path() to get the
final device path. But d_path() can return error, and in that case the next strscpy() call
will trigger an invalid memory access. Add back the missing error handling for d_path().
