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.
