3.19.8-ckt8 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Francesco Lavra <francescolavra.fl@xxxxxxxxx>
commit 0919e4445190da18496d31aac08b90828a47d45f upstream.
Commit f2147de33470 ("watchdog: sunxi: support parameterized compatible
strings") introduced a regression in sunxi_wdt_start(), by which
the system reset function of the watchdog is not enabled upon
starting the watchdog. As a result, the system is not reset when the
watchdog expires. Fix it.
