Subject: [PATCH AUTOSEL 5.5 114/542] watchdog: qcom: Use platform_get_irq_optional() for bark irq
Date: Fri, 14 Feb 2020 10:41:46 -0500
Message-ID: <20200214154854.6746-114-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>

From: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>

[ Upstream commit e0b4f4e0cf7fa9d62628d4249c765ec18dffd143 ]

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")
