Subject: [PATCH] power: gemini-poweroff: Fix IRQ check in gemini_poweroff_probe
Date: Thu, 20 Jan 2022 10:46:54 +0000 [thread overview]
Message-ID: <20220120104654.3467-1-linmq006@gmail.com> (raw)
platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:
int irq = platform_get_irq(pdev, 0);
if (irq < 0)
return irq;
Fix the check of return value to catch errors correctly.
Fixes: f7a388d6cd1c ("power: reset: Add a driver for the Gemini poweroff")
