2013-03-25staging: comedi: ni_labpc: fix labpc_eeprom_insn_read()H Hartley Sweeten
The comedi core expects the (*insn_read) operations to read insn->n values and return the number of values actually read. Make this function work like the core expects.

2013-03-25staging: comedi: ni_labpc: cleanup trigger setting in labpc_ai_cmd()H Hartley Sweeten
The (*do_cmdtest) already validated the cmd sources so the default cases in the switch() statements can never happen. Preclear to trigger bits and change the switch() statements to simple if() tests to set the bits.

For aesthetic reasons, move the labpc_counter_load() function so it's by the labpc_counter_set_mode() function.

2013-03-25staging: comedi: amplc_dio200: split into ISA, PCI and commonIan Abbott
Split the "amplc_dio200" comedi driver module into separate driver modules for ISA and PCI boards with a common module for the shared code. Keep the old name "amplc_dio200" for the ISA board driver as the module may be modprobed with this name by a script. (If the script uses insmod it will need modifying to load the "amplc_dio200_common" module first.) Use the module name "amplc_dio200_pci" for the PCI board driver. On most systems this will be auto-loaded. Use the module name "amplc_dio200_common" for the module containing the shared code. This is normally loaded as a dependency of the other two modules. "amplc_dio200_common" exports the following functions: * `amplc_dio200_common_attach()`: this is basically the old `dio200_common_attach()` from the combined driver module. It is called from the driver-specific attach or auto-attach routines. * `amplc_dio200_common_detach()`: this is most of the old `dio200_detach()`. It is called from the driver-specific detach routine. * `amplc_dio200_set_enhance()`: this is a new function called during initialization of PCIe cards to enable "enhanced" mode.
