From ecc33af33ea8f71e691db1c1000ead675dc4d34f Mon Sep 17 00:00:00 2001 From: Chase Southwood Date: Mon, 11 Aug 2014 21:02:58 -0500 Subject: [PATCH] staging: comedi: addi_apci_1564: remove apci1564_do_config The DO config function served the purpose of configuring the diagnostic interrupts for the board. As the driver currently does not support diagnostic interrupts, the digital output subdevice does not need an insn_config operation and this function can be safely removed.
