gpio: idt3243x: Fix an ignored error return from platform_get_irq()
The return from the call to platform_get_irq() is int, it can be a negative error code, however this is being assigned to an unsigned int variable 'parent_irq', so making 'parent_irq' an int. Eliminate the following coccicheck warning: ./drivers/gpio/gpio-idt3243x.c:167:6-16: WARNING: Unsigned expression compared with zero: parent_irq < 0 Reported-by: Abaci Robot <abaci@linux.alibaba.com> Fixes: 30fee1d7462a ("gpio: idt3243x: Fix IRQ check in idt_gpio_probe") Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>
