Subject: staging: comedi: addi_apci_1564: remove eeprom support code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4ae63178637d03bca6b58336ad3e4b3af9e60339;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: comedi: addi_apci_1564: remove eeprom support code

Reading the eeprom on this board is not necessary.  All information
required is in the boardinfo.

Remove the eeprom support code which is not really useful here.
