[PATCH 13/16] staging: comedi: cb_pcidas64: use comedi_pci_detach()

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

 



Use comedi_pci_detach() to handle the boilerplate part of the (*detach)
for this PCI driver.

This also fixes a race condition where the interrupt handler is released
before the interrupts are disabled in the hardware.
