From 045ec4123152e48b1047bb0e3ed316d924677e86 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Thu, 10 Sep 2015 17:24:59 +0530 Subject: [PATCH] staging: dgap: remove unused variable These variables were assigned some values but they were never used. Removed them but kept one call to ioread8() as it might affect the hardware.
