From fb7d94a7582e494a71c3a0b311910f7b179c01d9 Mon Sep 17 00:00:00 2001 From: Daeseok Youn Date: Wed, 6 Jul 2016 15:16:12 +0900 Subject: [PATCH] staging: dgnc: remove useless variable 'intr_count' The 'intr_count' variable was used only for increasing. So the 'intr_count' variable is not useful for this driver.
