2012-07-06staging: vt6656: int: Redundant blank line removalJesper Juhl
This trivial cleanup patch removes some completely redundant blank lines from drivers/staging/vt6656/int.[ch] Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-07-06staging: sm7xxfb: erase hardcode cast between smtcfb_info and fb_infoJavier M. Mellid
This patch erases hardcode cast between smtcfb_info and fb_info in order to get a more robust and less rigid smtcfb_info structure. fb_info doesn't need to be the first field in smtcfb_info after this patch. Tested with SM712. Signed-off-by: Javier M. Mellid <jmunhoz@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-07-06staging: comedi: s626: fix the number of dio channelsH Hartley Sweeten
The first digital i/o subdevice has its n_chan set to S626_DIO_CHANNELS which is defined as 48. This is actually the total number of channels provided by all three digital i/o subdevices. Each subdevice only has 16 channels. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-07-06staging: comedi: dmm32at: remove unneeded boardinfo variablesH Hartley Sweeten
Like most of the comedi drivers, this one appears to have been started based on the skel driver. Cut-and-paste from that driver has resulted in an unnecessarily complex boardinfo struct. Remove everything from the boardinfo struct, except the 'name', and just use the open coded values in the attach function.

2012-07-06staging: comedi: dmm32at: use module_comedi_driverH Hartley Sweeten
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 Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-07-06staging: comedi: das08_cs: refactor the pcmcia probe/removeH Hartley Sweeten
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.

The pcmcia support code in this driver is cut-and-paste from the dummy_cs.c driver of the Linux PCMCIA Card Services package. It has code in it to stop the device during suspend but nothing in the main comedi_driver uses it. Remove the 'stop' variable from the pcmcia private data and all the logic that deals with it.

2012-07-06staging: comedi: das08_cs: cleanup the pcmcia_driver declarationH Hartley Sweeten
For aesthetic reasons, add some whitespace to the declaration of the pcmcia_driver and reorder it a bit. Also, the symbol 'das08_cs_driver' is only referenced in this file, make it static.

2012-07-06staging: comedi: das_08: remove the 8254 'logic2phys' usageH Hartley Sweeten
The three 8254 timers have a 1:1 relationship to the comedi channels. The 'logic2phys' usage just makes the driver more complex. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-07-06staging: comedi: das_08: remove the cached 8254 'mode'H Hartley Sweeten
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.

2012-07-06staging: comedi: ni_670x: fix dereference of an invalid pointerH Hartley Sweeten
The attach if this driver can fail before the subdevices are allocated. If the attach fails the comedi core will call the detach routine to allow the driver to do it's cleanup.

2012-07-06staging: comedi: ni_670x: return '0' for successful attachH Hartley Sweeten

2012-07-06staging: comedi: adl_pci6208: fix the ao_readback variable sizeH Hartley Sweeten
The 'ao_readback' variable in the private data struct is used to cache the last value written to the analog output DAC channels. 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.
