    gpio: tb10x: Fix an error handling path in tb10x_gpio_probe()
    
    [ Upstream commit b547b5e52a0587e6b25ea520bf2f9e03d00cbcb6 ]
    
    If an error occurs after a successful irq_domain_add_linear() call, it
    should be undone by a corresponding irq_domain_remove(), as already done
    in the remove function.
