staging: comedi: amplc_pc236: don't disable h/w interrupt on detach()
If an asynchronous command was running when the device is being detached, the comedi core would have called the subdevice `cancel` handler (`pc236_intr_cancel()`) before calling the `detach` handler (`pc236_detach()`). Since the cancel handler disables hardware interrupts (at least for the PCI236 board) by calling `pc236_disable_intr()`, there is no need for the detach handler to do so as well. Remove the call to `pc236_disable_intr()` from `pc236_detach()`. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
