H Hartley Sweeten 99953ea1ec staging: comedi: dmm32at: remove dmm_inb macro
The macro is just a wrapper for inb(). Just use the inb() directly.

H Hartley Sweeten 47ae6a7259 staging: comedi: dmm32at: remove forward declarations 2
Move the dmm32at_ns_to_timer() and dmm32at_setaitimer() functions
to remove the need for the remaining forward declarations.

Also, make dmm32at_setaitimer() static, it's only referenced in
this file.

H Hartley Sweeten 17f49dd46c staging: comedi: dmm32at: use module_comedi_driver
Convert driver to use the module_comedi_driver() macro to remove
some of the boilerplate.

Move the comedi_driver variable to the end of the file to keep it
with the module_comedi_driver() macro. This also removes the need
for some of the forward declarations. While moving the variable:

1) strip out the unnecessary cut-and-paste skel driver comments
2) add whitespace to improve the readability
3) rename the variable from driver* to *driver

The 'thisboard' macro relies on a local variable having a specific

the macro with a local variable where used. Use the comedi_board()
helper to get the pointer.

H Hartley Sweeten ae6eba84ef staging: comedi: das08_cs: refactor the pcmcia probe/remove
Move the pcmcia_disable_device() call where needed in the pcmcia
probe/remove and delete the das08_pcmcia_release() function.

Move the logic of the das08_pcmcia_config() directly into the
probe function and properly return an error code when the config
fails.

Only set cur_dev, used by the comedi_driver, if the pcmcia probe
is successful. Also, make sure to NULL it in the remove.

Remove all the kernel messages in the pcmcia support code. They
are just added noise.

The pcmcia support code in this driver is cut-and-paste from the

H Hartley Sweeten cba9d4aa4e staging: comedi: das_08: remove the cached 8254 'mode'
The driver initially sets all the cached 'mode' values for the
8254 timers to (I8254_MODE0 | I8254_BINARY). It then sets the
timers to that 'mode'. Configuring the counters with the comedi
INSN_CONFIG_SET_COUNTER_MODE updates the 'mode' and then sets
the timers to the 'mode'. The cached value is never read or
used other than for storage.

Just remove the 'mode' usage as it serves no purpose.

The 'ao_readback' variable in the private data struct is used to

The PCI-6208 has 8 analog output channels but the variable only
allowed space to cache 2 values.

Since the PCI-6216 board could be supported by this driver and
it has 16 analog outputs, create a define for the maximum number
of channels and use that to set the size of 'ao_readback'.

For now, set the max to 8 to save space since the PCI-6216 is
not currently supported.

H Hartley Sweeten 9d639b6b25 staging: comedi: adl_pci6208: pass on the error code from comedi_pci_enable
Return the actual error code from comedi_pci_enable instead of
assuming -EIO on failure. Also, shorten the local variable name 'retval'
to 'ret'.

H Hartley Sweeten db7c275d9f staging: comedi: adl_pci6208: remove pci6208_pci_setup()
Refactor pci6208_pci_setup() into the attach function. This
function simply enables the pci device and gets the PCI iobase
address used by the driver. There's no need for a separate
function to handle this.

The "local configuration register" stuff is not required. The
io base/range are only queried for use in a kernel message
that it just added noise. Similar with the io range for the
actual io base used by the driver.

Remove both printk's and all the unnecessary code.

Add defines for the register map of the device. These will be
used to clarify the code.

H Hartley Sweeten 745c22a016 staging: comedi: adl_pci6208: remove the boardinfo 'ao_bits'
All the boards supported by this driver have 16-bit DACs. The
ao_bits variable in the boardinfo is commented out anyway.
Just remove it.
