Subject: watchdog: WatchDog Timer Driver Core - use passed watchdog_device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb7efc02c6dbc3bfe9d5d1509ed790fc757e05a9;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

watchdog: WatchDog Timer Driver Core - use passed watchdog_device

Use the passed watchdog_device instead of the static global variable when
testing and setting the status in watchdog_ping, watchdog_start, and
watchdog_stop.  Note that the callers of these functions are actually
passing the static global variable.
