gpio: mvebu: make mvchip->irqbase signed for error handling
There is a bug in mvebu_gpio_probe() where we do: mvchip->irqbase = irq_alloc_descs(-1, 0, ngpios, -1); if (mvchip->irqbase < 0) { The problem is that mvchip->irqbase is unsigned so the error handling doesn't work. I have changed it to be a regular int. Cc: stable@vger.kernel.org Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
