[ Upstream commit 522dceeb62ded1a7b538d2f1f61cc69a1402537d ]
On hbacmd reset failure, observing wrong string "nline" in kernel log.
On failure, non negative value (1) is returned from sysfs store
routine. It is interpreted as count by kernel and store routine is
called again with the remaining characters as input.
Fix: Return negative error code (-EIO) in case of failure.
