LoongArch: Fix unsigned comparison with less than zero
The return value from the call to get_timer_irq() is int, which can be a negative error code. However, the return value is being assigned to an unsigned int variable 'irq', so making 'irq' an int. Eliminate the following coccicheck warning: ./arch/loongarch/kernel/time.c:146:5-8: WARNING: Unsigned expression compared with zero: irq < 0 Reported-by: Abaci Robot <abaci@linux.alibaba.com> Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
