Kartik RajputandGreg Kroah-Hartman 369edea60f clocksource/drivers/timer-tegra186: Fix support for multiple watchdog instances ...

commit ca57bf46e7 upstream.

Tegra SoCs support multiple watchdogs; currently only one (WDT0) is
used. When multiple watchdogs are registered, tegra186_wdt_enable()
overwrites the TKEIE(x) register, discarding any existing watchdog
interrupt enable bits. As a result, enabling one watchdog inadvertently
disables interrupts for the others.

Fix this by preserving the existing TKEIE(x) value and updating it
using a read-modify-write sequence.
