Subject[PATCH] watchdog: qcom: Use platform_get_irq_optional() for bark irq
Date
platform_get_irq() prints an error message when the interrupt
is not available. So on platforms where bark interrupt is
not specified, following error message is observed on SDM845.

[ 2.975888] qcom_wdt 17980000.watchdog: IRQ index 0 not found

This is also seen on SC7180, SM8150 SoCs as well.
Fix this by using platform_get_irq_optional() instead.

Fixes: 36375491a4395654 ("watchdog: qcom: support pre-timeout when the bark irq is available")
