Subject: staging: comedi: addi_apci_3200: remove i_APCI3200_ConfigDigitalOutput()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e9840e632a2fd22b3af4a2593df49dcc94923e50;p=deliverable%2Flinux.git

staging: comedi: addi_apci_3200: remove i_APCI3200_ConfigDigitalOutput()

The digital outputs of the board supported by this driver are not
configurable. This driver abuses the comedi API and uses the 'insn_config'
function of the digital output subdevice to enable/disable writing to
the eeprom on the board. Remove this function.
