New smatch warnings: drivers/usb/typec/tcpm/tcpci_maxim.c:324 max_tcpci_irq() error: uninitialized symbol 'irq_return'. drivers/usb/typec/tcpm/tcpci_maxim.c:407 max_tcpci_probe() warn: passing zero to 'PTR_ERR' The change fixes the above warnings by initializing irq_return and replacing IS_ERR_OR_NULL with IS_ERR.
