    Subject[PATCH 4.19 016/639] watchdog: sprd: Fix the incorrect pointer getting from driver data
    Date
    From: Shuiqing Li <shuiqing.li@unisoc.com>

    commit 39e68d9e7ab276880980ee5386301fb218202192 upstream.

    The device driver data saved the 'struct sprd_wdt' object, it is
    incorrect to get 'struct watchdog_device' object from the driver
    data, thus fix it.

    Fixes: 477603467009 ("watchdog: Add Spreadtrum watchdog driver")
