staging: comedi: pass subdevice to comedi_buf_put() Change the parameters of `comedi_buf_put()` to pass a pointer to the comedi subdevice instead of a pointer to the "async" structure belonging to the subdevice. The function puts a sample value in the comedi buffer, but currently only deals with 16-bit sample types. A future version could deal with 16 or 32-bit sample types depending on the value of the SDF_LSAMPL subdevice flag. The main aim at the moment is to replace all the `struct comedi_async *` parameters with `struct comedi_subdevice *` parameters in the comedi driver API.

staging: comedi: drivers: properly validate cmd->scan_end_arg When the async command 'scan_end_src' is TRIG_COUNT the 'scan_end_arg' is the cmd->chanlist_len. Fix a couple open-coded drivers. Add the check to the drivers that do not validate this command argument. The core validates that the cmd->chanlist_len is <= s->len_chanlist. During the post config after the attach the core also make sure that the s->len_chanlist is initialized. For clarity, initialize the s->len_chanlist in a couple drivers that are relying on the core to initialize it to '1'.

Move the free_irq() into comedi_legacy_detach() so that the drivers don't have to deal with it. For drivers that then only call comedi_legacy_detach() in their private (*detach), remove the private function and use the helper directly for the (*detach). The amplc_pc236 and ni_labpc drivers are hybrid legacy/PCI drivers. In the detach of a PCI board free_irq() still needs to be handled by the driver. The pcl724 and pcl726 drivers currently have the free_irq() #ifdef'ed out. The comedi_legacy_detach() function sanity checks that the irq has been requested before freeing it so they are safe to convert. For aesthetic reasons, move the #ifdef unused chunk in the pcl816 driver up to the previous #ifdef unused block. The pcmio and pcmuio drivers request multiple irqs and handle the freeing of them. Remove the 'dev->irq = irq[0]' in those drivers so that comedi_legacy_detach() does not attempt to free the irq.

staging: comedi: export alloc_subdevices as comedi_alloc_subdevices Move the inline alloc_subdevices() function from comedidev.h to drivers.c and rename it to comedi_alloc_subdevices(). The function is large enough to warrant being an exported symbol rather than being an inline in every driver.

staging: comedi: cleanup all the comedi_driver 'detach' functions 1. Change the return type from int to void All the detach functions, except for the comedi usb drivers, simply return success (0). Plus, the return code is never checked in the comedi core. The comedi usb drivers do return error codes but the conditions can never happen. The first check is: if (!dev) return -EFAULT; This checks that the passed comedi_device pointer is valid. The detach function itself is called using this pointer so it MUST always be valid or there is a bug in the core: if (dev->driver) dev->driver->detach(dev); And the second check: usb = dev->private; if (!usb) return -EFAULT; The dev->private pointer is setup in the attach function to point to the probed usb device. This value could be NULL if the attach fails. But, since the comedi core is going to unload the driver anyway and does not check for errors there is no gain by returning one. After removing these checks from the comedi usb drivers the detach functions required a bit of cleanup. 2. Remove all the printk noise in the detach functions All of the printk output is really just noise. The user did a rmmod to unload the driver, we really don't need to tell them about it. Also, some of the messages are output using: dev_dbg(dev->hw_dev, ... or dev_info(dev->hw_dev, ... Unfortunately the hw_dev value is only used by drivers that are doing DMA. For most drivers this variable is going to be NULL so the output is not going to work as expected. 3. Refactor a couple static 'free_resource' functions into the detach functions. The 'free_resource' function is only being called by the detach and it makes more sense to just absorb the code. 4. Remove a couple unnecessary braces for single statements. 5. Remove unnecessary comments. Most of the comedi drivers appear to be based on the comedi skel driver and have the comments from that driver included. These comments make sense in the skel driver for reference but they don't need to be in any of the actual drivers. 6. Remove all the extra whitespace. It's not needed to make the functions any more readable. 7. Remove the now unused 'attached_successfully' variable in the cb_pcimdda driver. This variable was only used to conditionally output some driver noise during the detach. Since all the printk's have been removed this variable is no longer necessary.

staging: comedi: refactor comedi_parport driver and use module_comedi_driver Move the module_init/module_exit routines and the associated struct comedi_drive to the end of the source. This is more typical of how other drivers are written and removes the need for the forward declarations. Convert the driver to use the module_comedi_driver() macro which makes the code smaller and a bit simpler.
