Rename the local variable used for the private data pointer to the comedi "norm". Remove the unnecessary sanity check of the private data pointer. This function can only be called is the private data was allocated during the attach. Make sure an ao command is not already running and return -EBUSY. Tidy up the exit path using goto to ensure that the semaphore is released. Signed-off-by:

This function can only be called is the private data was allocated during the attach. Tidy up the exit path using goto to ensure that the semaphore is released. Return -EBUSY instead of 0 if the (*insn_write) cannot be done because a command is running. Tidy up the for() loop that writes the data. The dux_commands[1] and [4] can be set outside the loop since they are constant. Use a local pointer for dux_commands[2] to load the value to write. Only the last value needs to be cached in the private data for read back. Signed-off-by:

Use the comedi_range_is_bipolar() helper instead of checking the 'range' index against a magic number. Also, use the s->maxdata to calculate the value needed to munge the value for bipolar data instead of the magic number. Signed-off-by:

As pointed out by Ian Abbott, the *_cmd_running flags should be set before submitting the urbs. There is a possible race condition where an urb could complete and the flag is checked in the completion routine before it's set. Reported-by:

The COMEDI_NI_ATMIO configuration option causes the "ni_atmio" module to be built, which handles various National Instruments ISA-PNP data acquisition cards. The configuration option currently depends on ISAPNP. The "ni_atmio" module is a "legacy" comedi driver with no auto-configuration support and it doesn't register as a PNP card driver. The only difference in initialization from the other comedi ISA card drivers is that it will use the ISA-PNP functions to find, attach and activate the card if no I/O base address has been specified by the user in the COMEDI_DEVCONFIG ioctl. The module compiles fine without the ISAPNP configuration option as the <linux/isapnp.h> and <linux/pnp.h> headers provide dummy inline functions if the ISAPNP and PNP options, respectively, are not enabled. Remove the dependancy on the ISAPNP option since the module builds without it and can be used without it. (There is a very slim chance that comedi will support proper ISA PNP drivers one day, in which case the ni_atmio driver could be converted to use this support and not support manual configuration. However, not all the PnP IDs of boards supported by this driver are currently known to us.) Signed-off-by:

The COMEDI_NI_ATMIO16D configuration option causes the "ni_atmio16d" module to be built, which handles the National Instruments AT-MIO-16 and AT-MIO-16D cards. The configuration option currently depends on ISAPNP, but the module doesn't use any ISAPNP functions and the cards are legacy ISA cards with base I/O port, IRQ and DMA channel configured by jumpers. (The driver doesn't use DMA though.) Remove the ISADNP dependancy from COMEDI_NI_ATMIO16D and fix up the help text - the card names are missing a dash and they're not ISA-PNP. Signed-off-by:

As reported, this driver causes problems when built into the kernel, so force it to be a module until those issues are fixed. Also delete the "default n" lines in the Kconfig, as they are not needed. Reported-by:

This is the driver for Xillybus, which is a general-purpose interface for data communication with FPGAs (programmable logic). Please refer to the README included in this patch for a detailed explanation. It was previously submitted for misc-devices, but it appears like noone's willing to review the code (which I can understand, given its magnitude). Hence submitted as a staging driver. Signed-off-by:

The resolution of msleep is related to HZ, so with HZ set to 100 any msleep of less then 10ms will become ~10ms. This is not what we want. Use usleep_range to get more control of what is happening here. Signed-off-by:

There was some code that cleared the dma_mask when dma was disabled in the driver. Given that clearing the mask doesn't actually tell the usb core we're not using dma, and a previous commit explicitely sets the hcd->self.uses_dma value, it seems these values are unneeded and can only potentially cause problems (when reloading a module, for example).

This thing seems to do some kind of delayed setup. Really, real kms drivers shouldn't do that at all. Either stuff needs to be dynamically hotplugged or the driver setup sequence needs to be fixed. This patch here just moves the setup at the very end of the driver load callback, with the locking adjusted accordingly. v2: Also move the corresponding put from ->lastclose to ->unload.

Tidy up the multi-line comments at the beginning of the file and remove any irrelevant information. Fix the II20K_ID_PCI200341M_1 define, there are one to many 0's. Rename all the remaining pci20xxx_* to ii20k_*. The "pci" just adds confusion, this is not a PCI board. Remove the private (*detach) function. It's safe to call the comedi core provided comedi_legacy_detach() even if there is nothing to cleanup. Signed-off-by:

The PCI-200341M-1 module can both provide an analog input subdevice in this driver. The module provides four differential input channels with four programmable gains. Currently the gain is configured as an option passed when the board is attached. Rewrite the ai subdevice support functions to properly handle the programmable gain. For aesthetics, redefine the memory map for the module. Signed-off-by:

The PCI-20006M-1 and PCI-20006M-2 modules can both provide an analog output subdevice in this driver. Fix the module init code to detect both of them. The analog output can support +/-5, 0-10, or +/-10 volt ranges depending on jumpers on the board. Report all the ranges to the user instead of relying on the configuration options to set the range. The user can then select the appropriate range depending on how they have configured the hardware. Tidy up the (*insn_{read,write})() functions to work like the comedi core expects. Signed-off-by: -
