[PATCH v2 09/14] can: kvaser_pciefd: Change return type for kvaser_pciefd_{receive,transmit,set_tx}_irq()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Change return type to void for kvaser_pciefd_transmit_irq(),
kvaser_pciefd_receive_irq() and kvaser_pciefd_set_tx_irq().
These functions always return zero.
