#1282085 — [PATCH 3.19.y-ckt 133/164] hsi: fix double kfree

3.19.8-ckt11 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geliang Tang <geliangtang@163.com>

commit f098a045350ecd6045f2f2d5a50fecf2a98962d7 upstream.

When device_register() fails, kfree() is called in hsi_client_release(),
hence there is no need to call kfree in err3 again.

Fixes: a2aa24734d9db ("HSI: Add common DT binding for HSI client devices")
