Subject: staging: comedi: addi_apci_3120: remove eeprom handling code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=887f706edf86fe90d04f0df83704d612722e3d36;p=openwrt%2Fstaging%2Fblogic.git

staging: comedi: addi_apci_3120: remove eeprom handling code

The boards supported by this driver do not have an eeprom. Remove
the unnecessary code to handle it.
