pci_dev_put - release a use of the pci device structure SYNOPSIS
void pci_dev_put(struct pci_dev * dev); ARGUMENTS
dev device that's been disconnected DESCRIPTION
Must be called when a user of a device is finished with it. When the last user of the device calls this function, the memory of the device is freed. COPYRIGHT

STRUCT
INPUT_POLLED_(9) Input Subsystem STRUCT INPUT_POLLED_(9) NAME
struct_input_polled_dev - simple polled input device SYNOPSIS
struct input_polled_dev { void * private; void (* open) (struct input_polled_dev *dev); void (* close) (struct input_polled_dev *dev); void (* poll) (struct input_polled_dev *dev); unsigned int poll_interval; unsigned int poll_interval_max; unsigned int poll_interval_min; struct input_dev * input; }; MEMBERS
private private driver data. open driver-supplied method that prepares device for polling (enabled the device and maybe flushes device state). close driver-supplied method that is called when device is no longer being polled. Used to put device into low power mode. poll driver-supplied method that polls the device and posts input events (mandatory). poll_interval specifies how often the poll method should be called. Defaults to 500 msec unless overridden when registering the device. poll_interval_max specifies upper bound for the poll interval. Defaults to the initial value of poll_interval. poll_interval_min specifies lower bound for the poll interval. Defaults to 0. input input device structure associated with the polled device. Must be properly initialized by the driver (id, name, phys, bits). DESCRIPTION
Polled input device provides a skeleton for supporting simple input devices that do not raise interrupts but have to be periodically scanned or polled to detect changes in their state. COPYRIGHT
