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

From: Raag Jadav <raag.jadav@xxxxxxxxx>
[ Upstream commit cf38e7691c85f1b09973b22a0b89bf1e1228d2f9 ]
When built with CONFIG_INTEL_MID_WATCHDOG=m, currently the driver
needs to be loaded manually, for the lack of module alias.
This causes unintended resets in cases where watchdog timer is
set-up by bootloader and the driver is not explicitly loaded.
Add MODULE_ALIAS() to load the driver automatically at boot and
avoid this issue.
