| Subject: watchdog: qcom: Use platform_get_irq_optional() for bark irq |
| |
| From: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org> |
| |
| commit e0b4f4e0cf7fa9d62628d4249c765ec18dffd143 upstream. |
| |
| 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") |
