From: Yang Li <yang.lee@xxxxxxxxxxxxxxxxx> commit 7c1cf55577782725ea2bc24687767c8fe8e57486 upstream. 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@xxxxxxxxxxxxxxxxx> Fixes: 30fee1d7462a ("gpio: idt3243x: Fix IRQ check in idt_gpio_probe") Signed-off-by: Yang Li <yang.lee@xxxxxxxxxxxxxxxxx> Signed-off-by: Bartosz Golaszewski <brgl@xxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpio/gpio-idt3243x.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/gpio/gpio-idt3243x.c +++ b/drivers/gpio/gpio-idt3243x.c @@ -132,7 +132,7 @@ static int idt_gpio_probe(struct platfor struct device *dev = &pdev->dev; struct gpio_irq_chip *girq; struct idt_gpio_ctrl *ctrl; - unsigned int parent_irq; + int parent_irq; int ngpios; int ret; Patches currently in stable-queue which might be from yang.lee@xxxxxxxxxxxxxxxxx are queue-5.16/gpio-mpc8xxx-fix-an-ignored-error-return-from-platform_get_irq.patch queue-5.16/gpio-idt3243x-fix-an-ignored-error-return-from-platform_get_irq.patch
