gpio: adnp: Fix segfault if request_threaded_irq fails
In case request_threaded_irq inside adnp_irq_setup fails, the driver segfaults. This is because irq_domain_remove is called twice with the same pointer. First time in adnp_irq_setup and then a second time after leaving adnp_irq_setup in the error path of adnp_i2c_probe inside adnp_teardown. This fixes this by removing the call to irq_domain_remove from adnp_irq_setup. Signed-off-by: Lars Poeschel <poeschel@lemonage.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
