Subject: staging: comedi: addi_apci_1032: remove unnecessary eeprom code
X-Git-Tag: firefly_0821_release~3680^2~1519^2~593
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b1b640a8d8f1f1111d393dd07c8453550fb7cfae;p=firefly-linux-kernel-4.4.55.git

staging: comedi: addi_apci_1032: remove unnecessary eeprom code

Now that this driver is separate from the "common" addi-data code,
the eeprom does not contain any information required to make this
driver work.

Remove the unneeded initalization of the 's_EeParameters' and the
code that reads the eeprom to fill in the parameters.

Also, since reading the eeprom is not really interesting, remove
the EEPROM subdevice.
