gpio: msm: make msm_gpio.summary_irq signed for error handling
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') Cc: stable@vger.kernel.org Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
