Subject: [patch] gpio: msm: make msm_gpio.summary_irq signed for error handling
Date: Thu, 07 Nov 2013 07:51:34 +0000 [thread overview]
Message-ID: <20131107075134.GI21844@elgon.mountain> (raw)
There is a bug in msm_gpio_probe() where we do:
msm_gpio.summary_irq = platform_get_irq(pdev, 0);
if (msm_gpio.summary_irq < 0) {
The problem is that "msm_gpio.summary_irq" is unsigned so the error
handling doesn't work. I've fixed it by making it signed.
Fixes: 43f68444bce7 ('gpio: msm: Add device tree and irqdomain support for gpio-msm-v2')
