Instead of mangling this function wouldn't be better to introduce a

The diff is convoluted, but the end result is clean:
static int gpiochip_irqchip_init_valid_mask(struct gpio_chip *gpiochip)
{
if (gpiochip->irq_need_valid_mask) {
gpiochip->irq_valid_mask =
kcalloc(BITS_TO_LONGS(gpiochip->ngpio),
sizeof(long), GFP_KERNEL);
if (!gpiochip->irq_valid_mask)
return -ENOMEM;
/* Assume by default all GPIOs are valid */
bitmap_fill(gpiochip->irq_valid_mask, gpiochip->ngpio);
}
if (gpiochip->line_need_valid_mask) {
gpiochip->line_valid_mask =
kcalloc(BITS_TO_LONGS(gpiochip->ngpio),
sizeof(long), GFP_KERNEL);
if (!gpiochip->line_valid_mask)
return -ENOMEM;
/* Assume by default all GPIOs are valid */
bitmap_fill(gpiochip->line_valid_mask, gpiochip->ngpio);
}
return 0;
}
Is this acceptable?
