From: Yang Li <yang.lee@xxxxxxxxxxxxxxxxx> commit 9f51ce0b9e73f83bab2442b36d5e247a81bd3401 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 'irqn', so making 'irqn' an int. Eliminate the following coccicheck warning: ./drivers/gpio/gpio-mpc8xxx.c:391:5-21: WARNING: Unsigned expression compared with zero: mpc8xxx_gc -> irqn < 0 Reported-by: Abaci Robot <abaci@xxxxxxxxxxxxxxxxx> Fixes: 0b39536cc699 ("gpio: mpc8xxx: Fix IRQ check in mpc8xxx_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-mpc8xxx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/gpio/gpio-mpc8xxx.c +++ b/drivers/gpio/gpio-mpc8xxx.c @@ -47,7 +47,7 @@ struct mpc8xxx_gpio_chip { unsigned offset, int value); struct irq_domain *irq; - unsigned int irqn; + int irqn; }; /* 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
