From Yuriy Kaminskiy:

Most filesystems (in particular - reiserfs, jfs, xfs, nfs); maybe,
some legacy installation of ext2/3 too) always return dirent->dt_type =
DT_UNKNOWN, so libsensors fails to parse /etc/sensors.d.
  Also, symlink (DT_LNK) can point to directory, or FIFO/socket/device
(very bad!) - current check insufficient anyways.

Fixed by always using stat() to check what each entry is, rather than
relying on dirent->dt_type.
