From 5f193d736551634c521c05c4896cefbdff8a2a19 Mon Sep 17 00:00:00 2001 From: Chase Southwood Date: Sat, 21 Jun 2014 17:25:17 -0500 Subject: [PATCH] staging: comedi: addi_apci_1564: remove unused static variables The global variables ui_InterruptStatus_1564 and ui_InterruptData are both set but never used. Just remove them from the driver.
