Hi Shreeya,

Thank you for the patch! Yet something to improve:

All errors (new ones prefixed by >>):

drivers/gpio/gpiolib.c: In function 'gpiod_to_irq':
drivers/gpio/gpiolib.c:3068:29: error: 'struct gpio_chip' has no member named 'irq'
3068 | if (gc->to_irq && gc->irq.gc_irq_initialized) {
| ^~
Exactly, because this check should go under ifdeffery.


Makes sense to me now. gc->irq.initialized must be checked inside
gpiochip_to_irq() wrapped around an ifdef CONFIG_GPIOLIB_IRQCHIP

Thanks Andy, I'll send a v3 with this change.
