Christian Lamparter f06f35c66f watchdog: qcom: fix kernel panic due to external abort on non-linefetch 
This patch fixes a off-by-one in the "watchdog: qcom: add option for
standalone watchdog not in timer block" patch that causes the
following panic on boot:

The WDT_STS (status) needs to be translated via wdt_addr as well.
