I've tested this patch with tcpci_rt1711h.c that will be sent out for
reviewing in the next patch after tcpci's modification is passed.
Because interrupt handler is registered in tcpci_rt1711h.c, here is
the place I didn't notice.
The interrupt handler for tcpci.c should be modified as following:
static irqreturn_t _tcpci_irq(int irq, void *dev_id)
{
- struct tcpci *tcpci = dev_id;
+ struct tcpci_chip *chip = dev_id;
- return tcpci_irq(tcpci);
+ return tcpci_irq(chip->tcpci);
}
